Operating principles of oilfield drilling desander

Hydrocyclonic desander, as solid-liquid separation process, has been widely used in a range of industries to including chemical, environment protection, pharmaceutical and food. It has been found that hydrocyclonic desander is a green physical water-treatment equipment with a lot of advantages:cost-effective, easy operation, maintenance free, one-off investment and no pollution.

Operating principles of desander

The separation is achieved by accelerated sedimentation. As the mixed drilling fluid with density differential ( consist of high-density and low-density streams) is passed through the rapidly rotating bowl, centrifugal force will moves the heavier particles to the bottom of the clone and discharged, while the lighter fluids will be flowed through top overflow.
FEATURES AND APPLICATIONS
1,Simple structure, cost-effective, easy to install and operate and few maintenance.
2,Small footprint but high capacity.
3,Application scope: sand-removal in river and well, solid-liquid separation in coal washing and mineral processing, liquid-degassing and in the separation of immiscible liquids.
4,Application fields: air-condition water-treatment, chemical, petroleum, mineral,pharmaceutical, textile and other fields.
INSTALLATION REQUIREMENTS:
1,Fixed the solids control equipment on the base deck with three foundation bolts. The base deck should be made of concrete.
2,The base deck should be flat, or fixing the equipment on the flat floors.
3, pipe installation and the direction of flow
THE INSTRUCTIONS
1,Don’t close the inlet & outlet valves but close the sand-discharging valves during normal operation
2,Open the sand-discharging valves until the water runs cleaner when discharging.
3,Close the sand-discharging valves after discharging.。
4,Close the outlet valves when the pressure of sand-discharging valves are insufficient.
notes on security
5,Unauthorized disassemble is unadvisable.
6.Hdrocyclonic desander should be installed downstream from the centrifugal pump.
7,Water added with corrosion inhibitor should be fed into the clones before stopping the long-running operation to reduce corrosion and protect the solid control system.

desander is used as the 2nd stage of solids control system"

KOSUN desander is used as the 2nd stage of solids control for drilling mud, which makes separations between 45 and 75 microns. Desanders have no moving parts. The larger the internal diameter of the desander is, the greater the amount of drilling fluids it is able to process and the larger the size of the solids removed. A desander with a (10 inches (250 mm) cone) is able to remove 50% of solids within the 40-50 μm (micrometre) range at a flow rate of 500 US gallons per minute (32 L/s), whilea desilter (4 inches (100 mm) Cone) is able to remove 50% of solids within the 15-20 μm range at a flow rate of 60 US gallons per minute (3.8 L/s). Micro-fine separators are able to remove 50% of solids within the 10-15 μm range at a flow rate of 15 US gallons per minute (0.95 L/s). A desander is typically positioned next-to-last in the arrangement of solids control equipment, with a decanter centrifuge as the subsequent processing unit. Oilfield mud desander s are preceded by gas busters, gumbo removal equipment (if utilized), shale shaker, mud cleaner (if utilized) and a vacuum degasser. Desanders are widely used in oilfield drilling. Practice has proved that hydrocyclone desander is a kind equipment of economic and effective.

Features & Benefits for vertical centrifuge

 

 

The KOSUN vertical centrifuge uses centrifugal force to dry drilled solids in oil or synthetic base fluids. A stainless steel screen bowl traps “wet” solids and accelerates them up

 

900RPM. Liquid is forced through the screen bowl openings, while “dry” solids are extracted by the angled flights attached to the cone, which rotate slightly slower than the bowl.

 

Tungsten carbide protects the flights from abrasive solids and ensures long operational life. This aids in maintaining a constant gap between the scroll and screen bowl, which is crucial

 

for proper operation. KOSUN cutting dryer has been done strict balance testing for all major rotary components to minimize vibration & noisy.

 

 

These orders including 6 Decanter Centrifuges,Drilling Shale Shakers,and oilfield desander desilters.

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.
