Drilling mud solids control equipment sale in Algeria

Solids control is a technique used in drilling rig to separate the solids in the drilling fluids that are crushed by the drill bits and carried out of the well surface. Normally solid control system is consist of five stages, including mud tank, shale shaker, vacuum degasser, desander, desilter, drilling centrifuge. Shale shaker is used to separate the big solids with diameter above 75μm, and 45~74μm for desander, and 15~44μm for desilter. Sometimes desander & desilter are combined as high efficient mud cleaner. When air enters into the drilling fluids, vacuum degasseris used to separate the air. If no air in the mud, the degasser would work as a big agitator. All these equipments are mounted on the top of thedrilling fluids mud tank. After separating the solids, the clean mud would be pumped into the borehole again.

shale shaker manufactures in India

Drilling shale shakers are components of drilling equipment used in many industries, such as coal cleaning, mining, oil and gas drilling. They are considered to be the first phase of a solids control system on a drilling rig, they are used to remove large solids also called cuttings from the drilling fluid, more commonly called “Mud” due to its similar appearance.

Shale shakers for sale in Pakistan

Drilling fluids are integral to the drilling process and, among other functions, serve to lubricate and cool the drill bit as well as convey the drilled cuttings away from the bore hole. These fluids are a mixture of various chemicals in a water or oil based solution and can be very expensive to make. For both environmental reasons and to reduce the cost of drilling operations drilling fluid losses are minimized by stripping them away from the drilled cuttings before the cuttings are disposed of, this is done using a multitude of specialized machines and mud tanks.
Shale shakers are the primary solids separation tool on a rig. After returning to the surface of the well the used drilling fluid flows directly to the shale shakers where it begins to be processed. Once processed by the shale shakers the drilling fluid is deposited into the mud tanks where other solid control equipment begin to remove the finer solids from it. The solids removed by the shale shaker are discharged out of the discharge port into a separate holding tank where they await further treatment or disposal.
Shale shakers are considered by most of the drilling industry to be the most important device in the solid control system as the performance of the successive equipment directly relates to the cleanliness of the treated drilling fluid.

Centrifugal pump is a subclass of turbomachinery technology

Centrifugal pump is a subclass of turbomachinery technology. The main work of this type of pump is to bring up fluids through the transformation of the rotational energy into another energy called hydrodynamic energy. Typically, the rotational energy source is either the turbine, electric motor or engine. 

The term centrifugal force pertains description of the movement of energy that is from the impeller's mechanical rotational phase to the fluid's pressure and motion. However, the term centrifugal force is not always required to be used in describing the working mechanism of a particular centrifugal pump. Much like the other pumps, centrifugal pumps are indeed useful despite some criticisms and controversies. 

The cantilever pumps or vertical centrifugal pumps are likewise known in many industries. The main feature of this quality pump is the utilization of a special type of shaft and bearing configuration which permit the hanging up of volute just in the sump. Also, this pump model uses throttle bushing, instead of stuffing box in sealing the shaft. In most "parts washer," cantilever pumps are often used. 

Also, the forth pumps are widely used in oil and mineral industries. The issue concerning the use of this type of pump has something to do with the air content of froth, which blocks conventional pumping force. This problem was vigorously addressed by the oil industry through different approaches. The first approach involved the use of vertical pump with a built-in tank; the second approach involved the creation of a pump that has a built-in impeller capable of tearing air bubbles into pieces. 

Looking at the paper and pulp industry, holes are mainly done on the pump's impeller. The mechanism is simple: While the air goes out at the rear side of the impeller, an expeller discharges it back to the pump's suction mud tank. The vanes--either secondary vanes or split vanes--may be incorporated in the impeller. 

Regarding the mechanism of a multi-stage decanter centrifugal pump, usually the impellers are mounted either on different shafts or on a single shaft. It is called multi-stage simply because the device has more than one impellers. In addition, for the device to produce higher rate of flow output, the impellers may be adjoined in a parallel manner; and to generate higher level of pressure at the device' outlet, the impellers may be adjoined in series. Often, multi-stage decanter centrifugal pumps are used in boiler feed-water pumps and other similar pumping needs. 

The desander is primarily and widely applied in the petroleum industry

The desander is the two-level solids control equipment used for drilling fluid treatment. The desanderdesilter is mainly used for separating those solid particles with the granularity of 47 to 76 microns in the drilling fluid.
structure of desander 

The desander system is made up of the screening system, the adjusting and supporting system, the aqueduct, the foundation, the pressure gauge as well as the desander hydrocyclones.
The desander is primarily and widely applied in the petroleum industry, the oil and gas drilling, the exploration industry, the trenchless engineering, the geotechnical engineering, mining, metallurgy, coal as well as the hydroelectric industry. KOSUN MACHINERY is a professional solids control solution company which specializes in solids control equipment and system.

Desander is generally divided into the drilling mud desander, the drilling fluids desander and the hydrocyclone desander.

The hydrocyclone desander is operated in accordance with the principle of centrifugal separation. Since the water inlet tube is installed at the eccentric position of the cylinder, the water will first form into the downward inclined fluid along the tangent direction of the cylinder when it enters into the inlet tube through the hydrocyclone desander. The water flow will go downward in the spinning direction and in turn rotate upward along the axis of the cylinder when it reaches a certain position of the cone. Finally, the water flow will get discharged through the outlet pipe. Under the influence of the inertial centrifugal force from the water flow and their own gravity, those sundries will drop into the cone refuse vessel at the bottom of the equipment. With such advantages as high efficiency in decontamination, small drag coefficient, convenience in sewage disposal and reliable performance, the hydrocyclone desander can realize trash cleaning in operation with the water pump open.
As an auxiliary device in the petroleum drilling, the drilling fluids desander is mainly used for eliminating the rock debris and sand carried by the drilling fluid from the stratum in the process of drilling operation. The drilling fluids desander is made up of the tube for liquid inlet, the cone bucket for sand draining as well as the sand draining mouth. There are rotating parts installed in the cone bucket for sand draining, the supporting wall of which is equipped with separating windows. The upper supporting wall, a set of tapered slot as well as the tube for liquid inlet of those rotating parts make up the ascending components for the drilling fluid. Vanes of the desander are placed at the inner bottom of the rotating component and the sand draining regulator controls the amount of the drained sand. The drilling fluid enters into the rotating component through the liquid inlet tube and goes through centrifugal rotation by vanes. Those sand grains get separated from the drilling fluid when the fluid ascends to the separating window, through which the grains will be drained into the cone bucket. The drilling fluid after separation will enter into the ascending component and then flow into the groove through the liquid outlet of the cone slot.
As one of the indispensable and important devices for stabilizing and regulating those technical indicators of the drilling fluid, the drilling mud desander has also been extensively used in the tertiary purification of the drilling fluid. As the combination of the hydrocyclone desander and the vibrating screen, the drilling mud desander is the three-level solids control equipment used in the solid control system of the drilling fluid. It is primarily made up of the vibrating screen, the distribution manifold as well as the hydrocyclones. The drilling mud desander is mainly used to remove the harmful solid phase with the granularity of more than 15 microns so as to ensure the good properties of the drilling fluid.

Shale shakers consist of the following parts

Shale shakers consist of the following parts:
Hopper – The Hopper, commonly called the “base” serves as both a platform for the shaker and collection pan for the fluid processed by the shaker screens, also known as “underflow”. The hopper can be ordered according to the needs of the drilling fluid, aka “mud” system. It can come in different depths to accommodate larger quantities of drilling fluid as well as have different ports for returning the underflow to the mud system.
Oil well Shaker
Feeder- The Feeder is essentially a collection pan for the drilling fluid before it is processed by the shaker, it can come in many different shapes and sizes to accommodate the needs of the mud system. The most commonly used feeder is known as the weir feeder, the drilling fluid enters the feeder usually through a pipe welded to the outside wall near the bottom of the feeder tank, it fills the feeder to a predetermined point and like water flowing over a dam the mud (drilling fluid) spills over the weir and onto the screening area of the shaker. This method of feeding the shaker is most widely used due to its ability to evenly distribute the mud along the entire width of the drilling fluid shaker allowing for maximum use of the shaker’s screening deck area.
Some feeders can be equipped with a bypass valve at the bottom of the feeder which allows the drilling fluid to bypass the shaker basket and go directly into the hopper and back into the mud system without being processed by the shaker screens.
Screen Basket- Also known as the screen “bed” it is the most important part of the machine, it is responsible for transferring the shaking intensity of the machine, measured in “G’s”, while keeping the “shaking” motion even throughout the entire basket. It must do all that while holding the shale shaker screens securely in place, eliminating drilled solids bypass to the hopper and allowing for easy operation and maintenance of the machine. Different brands of shakers have different methods of fulfilling these demands by using specialized screen tensioning apparatus, rubber seals around the screens, basket reinforcement to limit flex, rubber Float Mounts rather than springs, rubber Deck seals and selective vibrator placement.
New Shale Shakers
Basket Angling Mechanism- The shaker basket must be capable of changing its angle to accommodate various flow rates of drilling fluids and to maximize the use of the shaker bed, this is where the angling mechanism plays an important part. The drilling fluid flowing over the shaker bed is designated into two categories:
Pool: Which is the area of the screening deck that consists mostly of drilling fluid with drilled cuttings suspended within it.
Beach: Is the area where the fluid has been mostly removed from the cuttings and they begin to look like a pile of solids.
As a rule of thumb the Beach and pool are maintained at a ratio of 80% pool and 20% beach, this of course can change depending on the requirements of cutting dryness and flow rates.
There are various angling mechanisms currently in use which vary from hydraulic to pneumatic and mechanical, they can be controlled from either one side of the shaker or must be adjusted individually per side. Mechanical angling mechanisms can be very dependable often requiring less maintenance but usually take more time to operate than their hydraulic or pneumatic counterparts where as the hydraulic/pneumatic angling mechanisms are much faster to operate and require less a physical means of operation.
Vibrator- This is the device which applies the vibratory force and motion type to the shaker bed. A vibrator is a specialized motor built for the purpose of vibrating, While containing an electric motor to provide the rotary motion it uses a set of eccentric weights to provide an omnidirectional force. To produce the proper Linear motion a second, counter rotating, vibrator is added in parallel to the first. This is what gives us the linear motion, “high G” shaking of the basket.

fully understand how a decanter centrifuge operates

In order to fully understand how a decanter centrifuge operates, we must first define what a centrifuge does. In many industrial jobs, solid material often mixes with liquids, contaminating water supplies or turning mud into sludge. A decanter centrifuge is useful in that it separates solids and liquids, and has become an essential component of water waste facilities and the chemical, oil, and food processing industries.

There are several types of decanter centrifuges currently utilized in the industry, the most common of which are vertical, horizontal and conveyor centrifuges. The principle behind a decanter centrifuge is based on the theory of gravitational separation. For example, if you fill a glass with a mixture of mud water, over time the weight of the mud will cause it to settle down at the base of the glass. With the mud congealed at the bottom, the water will be forced upwards, creating a clear separation between the two.

A decanter centrifuge employs the same principles of gravitational force. However, unlike the glass mixture, the process is expedited through the use of continuous rotation. In fact, rotation provides anywhere from 1000 to 4000 times the normal gravitational force, reducing the time required for separation from hours to seconds.

The concept of rotational separation is similar to rides found at amusement parks and county fairgrounds. In these rides, placing yourself at an angle allows you to overcome the gravitational forces induced by rotation. Similarly, a decanter centrifuge is essentially a bowl tube that rotates at an extremely high speed. The bowl tube is equipped with an internal conveyor which moves in the same direction but at a different velocity.

Decanter centrifuge working principle

Step 1: The slurry is inserted into the centrifuge through a connecting pipe and onto a conveyor.

Step 2: Utilizing an internal feed compartment, the conveyor ushers the slurry through a nozzle into the bowl area.

Step 3: The bowl rotates at high speeds to induce gravitational forces.

Step 4: High speed rotation separates the solid material from the liquid in a matter of seconds.

Step 5: The conveyor delivers the solid material upwards where it is discharged through a nozzle.

Step 6: The solid material removed, the purified liquid is released from a separate output.

The ability to purify a liquid makes decanter centrifuges ideal for waste water treatment facilities. However, there are variety of industries for which such centrifuges play an important role. Similar to other solids control equipment, centrifuges are simple to install and do not require a foundation to build upon. Their efficiency saves time and materials and is an essential component for many blue collar industries.

Shale shaker screen by KOSUN in Vietnam

KOSUN provides shale shaker in the process of using running plasma problem causes and solutions for your reference:
Analysis: this phenomenon, mainly with high content of solid phase drilling fluids, mud viscosity, dispersion cuttings were sieved material factors; shaker vibration force with small, high mesh sieve, screen the small size of their own conditions concerning; shaker and field installation of the inlet direction and location have a great relationship,

you can analyze the following step by step from several points:vibrating screen manufacturers
1, selected sieve size unreasonable. Each shaker processing capacity of 50L / s, it is because the processing capacity of the test conditions are based on national standards: selection screen of 60 mesh, increase in the proportion of 1.8 tested slurry, slurry viscosity of the slurry containing different particle size sand. As quickly got into the surface layer, resulting in a large number of solid-phase occupies an effective screen area and thus can not Asai segment shaker with a fine sieve. Thus, the initial drilling holes larger screen should be used, and as the drilling depth increases, the gradual introduction of fine mesh.crushing and screening plant
2, formation and mud conditions affect processing capacity. As the drilling fluid can not fully dissolved drug added, the paste in the sieve, run time of a serious phenomenon of slurry. And other drugs should be fully dissolved before use, or the use of larger mesh screen. Alternatively, when the drill rock or sand loose sand layer, the sand screen easily stuck in the hole, causing the blocking phenomenon sieve. Therefore, to test several different mesh sieve sieve to reduce the blocking phenomenon.
3, check the motor rotation is correct. First, remove the vibrator shield, check the two motors are both eccentric rotation outward rotation. Secondly, if the steering error, please exchange electronic control box into the line supply in any two phase lines. Wrong way one (two motor rotation toward the inside), although it can exclude outward cuttings, but slow; wrong way two (two co-rotating motors), vibration force is very small, basically does not handle row of sand slurry .
4, check the shaker amplitude. Vibration amplitude greater processing capacity is relatively more generally; factory vibration force adjusted to 90%. If running plasma condition can be aligned with the inner and outer eccentric angle, the vibration force is 100%. (Mud treatment time increased by only about 15%)
5, check the flow distribution in the sieve frame is reasonable. Crochet mesh structure of the shaker, lower than the middle on both sides of the screen surface, mud flows easily lost on both sides and run, should ensure that the mud from the middle into the shale shaker screen frame.
Workaround: You can use two scenarios:
First, adjust the front spring seat, the front of the screen box appropriately elevated angle;
Two is to adjust the position of extending slot flip board, solids control the flow distribution.

The vacuum pump moves the escaping gas from the vessel discharging

A vacuum degasser is a device used in drilling to remove gasses from drilling fluid which could otherwise form bubbles.

A vacuum degasser is a device used in drilling

For small amount of entrained gas in a drilling fluid, the vacuum degasser can play a major role of removing small bubbles that a liquid film has enveloped and entrapped. In order for it to be released and break out the air and gas such as methane, H2S and CO2 from the mud to the surface, the drilling fluid must pass degassing technique and it can be accomplished by the solids control equipment called degasser which is also a major part of a mud systems.
Vacuum degasser type is the most common form of degasser. It can be horizontal, vertical or round vessel. A vacuum action is created to pull in the gas cut mud. When the liquid enters the mud tank it will flow and be distributed to a layer of internal baffle plates designed for the mud to flow in thin laminar film and is exposed to a vacuum that forces the gas to escape and break out of the mud.The vacuum pump moves the escaping gas from the vessel discharging it to the rig’s flare or environmental solids control system.
