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, 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 degasser is 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 the mud tank. After separating the solids, the clean mud would be pumped into the borehole again.
Shale Shaker
The shale shaker is the first stage of solids control equipment in drilling purification system. It can remove cuttings above 75μm brought from the drilling well to leave the liquid with smaller particles into the tanks below, which will flow into next grade solids control equipment to be treated.
The Economy of Linear Motion
KOSUN linear motion shaker is especially effective while drilling top-hole sections where heavy and high-volume solids are usually encountered. In these intervals, shakers may generate powerful G-forces and its effective vibrating motion can quickly remove the dense solids from screens and particles from wells.
Features & Benefits
1. G-forces linear motion up to 7.4 G(adjustable depending on the situation)
2. Hi-speed conveyance of cuttings
3. Higher shaker-fluids capacity
4. Able to process heavier solids loads
5. Enhances cuttings processing volume
6. AWD device from -1°~5°
7. Single side screens tension system to easily change the screens
8. Shaker feeder can be weir type and header box
9. Hook-strip screens can be PMD and PWP screens
Decanter Centrifuge
KOSUN DC series decanter centrifuge is used in separating suspension of solids phase with particle diameter(d≥2μm) for drilling mud and fluids handling. Ruggedly built for oilfield and industrial services, it is especially effective in environmentally sensitive areas. It delivers high fluid-recovery rates and efficient solids control to significantly reduce the costs of makeup fluids and disposal. The centrifuge must test the dynamic balance for smooth operation over long periods.Speed ranging from 0 to 3900 RPM, generating centrifugal forces reach up to 3000G.
Features & Benefits
1. Innovative design includes longer bowl for increased retention time, resulting in drier solids and finer cut points.
2. Big bowl Big Volume, high G force available.
3. Stainless steel bowl, scroll, compartment and cover resist corrosion and provide long service life.
4. Tungsten carbide scroll points with wide spacing flights at tapered end create a finer layer of conveyed solids for consistent, uniform separation and maximum solids control efficiency.
5. German FAG or Sweden SKF brand bearings.
6. Electrical Components: SIEMENS/Schneider ATEX or IEC Ex for option.
7. Screw pump & centrifugal pump feeding pump option available to meet different application.
KOSUN has been providing a complete line of Solids Control Equipment for the Oilfield Industry and the Environmental Industry for over 20 years.KOSUN provides all the solids control equipment,such as mud tank, vacuum degasser, desander, desilter,mud agitator,mud gun,shear pump,centrifugal pump,jet mud mixer,and product accessories,also offers the services and complete solids control system for the oilfield.
