The types and quantities of solids present in drilling mud solid control system

The types and quantities of solids (insoluble components) present in drilling fluids systems play major roles in the fluid’s density, viscosity, filter-cake quality/filtration control, and other chemical and mechanical properties. The type of solid and its concentration influences mud and well costs hole stability, These, in turn, influence the service life of bits, pumps, and other mechanical equipment.

Drilled solids, consisting of rock and low-yielding clays and addictive polymer, are incorporated into the mud continuously while drilling. To a limited extent, they can be beneficial before excess the tolerated concentration. Different mud densities require different strategies to maintain the concentration of drilled solids within an acceptable range. Whereas low mud densities may require only mud dilution in combination with a simple mechanical separator, high mud densities may require a more complex strategy:
chemical treatment to limit dispersion of the drilled solids (e.g., use of a shale inhibitor or deflocculant like lignosulfonate),
(b) more complex solids- removal equipment, such as mud cleaners and high-speed centrifuges .

Solids removal on the rig is accomplished by the following techniques: Shale shakers, desander , desilter, centrifuge. Each device is designed to remove a sufficient quantity and size range of solids.Often these are accomplished using separate devices, but sometimes these processes are combined, as in the case of the mud cleaner, which is a bank of hydrocyclones mounted over a vibrating screen. Another important hybrid device is the cuttings dryer (also called a rotating shaker), which is a centrifuge fitted with a cone-shaped shaker; Additional devices can help to enhance solids-removal efficiency. For example, a vacuum degasser is sometimes installed (before any centrifugal pumps, typically between the shakers and desanders) to remove entrained air that can cause pump cavitation and reduction in mud density.

Although,the solids-control equipment used on a rig is designed to remove drilled solids—not all solids—from a drilling fluid, perfect separation of desired from undesired solids is not possible, the advantages offered by the solids-control equipment far outweigh their limitations. Solids removal is one of the most important aspects of mud system control, since it has a direct bearing on drilling efficiency and represents an opportunity to reduce overall drilling costs.The key to efficient solids control is to use the right combination of equipment for a particular situation, arrange the equipment properly, and ensure that it operates correctly.

Mid-East Client Visits KOSUN Factory and Reaches Agreement-oilfield decanter centrifuge

On Oct 28th, representative of a globally-renowned Middle-Eastern oil company came for an one-day inspection visit in KOSUN solid control factory on its invitation and reached a positive agreement on product cooperation with KOSUN.

Mid-East Client Visits KOSUN Factory and Reaches Agreement

Middle-Eastern Clients Visiting KOSUN Factory

During the visit, the Middle-Eastern client had a thourough inspection in KOSUN factory about its capability, technological prowess, R&D ability, sales team, after-sale services and so on. Through inspection and communication, the MIddle-Eastern client took a heavy interest in KOSUN and finally decided to make KOSUN her company’s qualified decanter centrifuge supplier.

This time, the Middle-Eastern client made the final decision of two sets of DC 355 Variable Frequency Centrifuge and talked about the basic technical details of the bulk centrifuges and drilling mud system for next year.

Drilling mud system

The Middle-East Region has always been an important partner overseas ever since KOSUN obtained the right to operate import and export trade in 2007. In 2012, in order to further strengthern Middle-East market and provide rapid sale and after-sale services, KOSUN Kazakhstan Solid Control Equipment Factory was successfully completed in Aktobe and put into service, whose establishment greatly enhanced its expansion in Middle-East Region.

It will be another successful advancement during KOSUN’s expansion in Middle-East market that the client from the renowned Middle-Eastern drilling company came to visit KOSUN and reached an agreement on cooperation, which is of great significance for KOSUN to cement the Middle-East market.

Big Success of KOSUN Market Expanding in Mexico-Solids Control

On 29th October, two clients from a subsidiary of PEMEX came to visit our factories in Xi’an. After viewing several production lines in Xi’an Jingwei Solids Control Equipment Factory and Xi’an Yongle Solids Control System Factory, the clients showed great satisfaction with KOSUN’s capabilities in manufacturing oil drilling solids control equipment, as well as good quality and excellent workmanship of the equipment.

Big Success of KOSUN Market Expanding in Mexico

Mr. Toby(in the middle) and Two Mexican Visitors(left and right) Coming Afar

In fact, these clients have been in contact with KOSUN since June of 2013, and sent an inquiry for 2 sets of solids control system in August. After keeping contact through phone and email for several months, they decided to come to visit KOSUN’s factories and also wanted to make the final decision for purchasing 2 sets of drilling fluids system. Because of our good quality products and superior service, the clients reached a cooperation agreement with KOSUN and signed a cooperation memorandum with our International Business Director Mr. Toby on 30th. What’s more, the clients promise to help KOSUN to promote its solids control equipment in Mexican market, and also show their expectation to be the exclusive agent of KOSUN in Mexico. For future cooperation, the Mexican clients suggest KOSUN to go and visit their workshop in Mexico and build a joint company with them in the local market.

International Business Staff and Two Mexican Visitors Coming Afar

China KOSUN VD series vacuum degasser of solids control system

Introduction of DC vacuum degasser
VD series Vacuum Degasser is a special-purpose device and a new type one for the treatment of gas in the drilling fluids. It can separate various gas in drilling fluid. Meanwhile, it will recover mud weight efficiently, keep drilling fluid property steady. Vacuum degasser also can be used as big mud agitator, and adaptable for various mud system.

The vacuum degasser is a high-efficiency in-line module that removes dissolved gases from HPLC solvents. Its unique design assures reliable continuous operation and the highest level of continuous performance available without the need for helium degassing. Up to five solvent lines may be degassed simultaneously by one unit. The extremely low internal volum of each Teflon AFchannle offers very quick equilibration and very short startup times compared with PTFE degassing channles which have the same degassing efficiency.

The work principle of vacuum degasser of drilling fluids system

The vacuum degasser uses the suction function of the vacuum pump to form the negative pressure in the vacuum tank. Under the pressure of atmosphere, the drilling fluid enters into hollow shaft from suction line, and then to be gathered by the umbrella slices around of the hollow shaft to toss to tank skin in spurting. With the impact of vacuum and bubble centrifuge, the bubble will be broken in the drilling fluid, the gas will escape and suction out by the vacuum pump and vent to the safety zone.

VD Vacuum Degasser is produced by kosun Machinery and is one of the most important Equipments forSolids Control. The vacuum degasser design of the structure is scientific and rational. So we are able to achieve an effective gas-liquid separation, filter out impurities and to ensure that the exhaust pipe is always smooth.

The degasser is used to clean up the gas in the drilling fluid, ensuring the performance of drilling fluid relatively stable and the proper functioning of swirler. It is the second level equipment in solid control system, and it will be set between shale shaker and mud cleaner/desander.
VD vacuum degasser has many features, which includes compact design, high performance/full vacuum, vacuum pump mounted together with degasser vessel, internal impellers, vertically-mounted units, without feed pump.
