Mud tanks play an important role in solids control system. It is the base of solids control equipments, and also the carrier of drilling fluids.
Solids control equipments that are all mounted on the top of mud tanks include the following:
1. shale shaker
2. vacuum degasser
3. desander
4. desilter
5. centrifuge
6. mud agitator
7. vertical slurry pump
Drilling fluids flow into the shale shaker directly after it returns to the surface of the well, and the solids that are removed by the screen would be dischanged out of the tank, and the drilling fluids with smaller solids would flow through the screen into mud tank for further purification. A centrifugal pump would sucks the shaker-treated fluids up to the desilter or mud cleaner for further purification. And vertical slurry pump is used to pump the drilling fluids up to the centrifuge,and mud pump would pump the drilling fluids from mud tank into the borehole after it is treated by centrifuge. And the circulation system would continues. The number of the mud tanks that are needed on the drilling rig depends on the depth of the well, and also the mud demands of drilling. Normally the shale shaker and vacuum degasser and desander are mounted together on the same mud tank as the first tank at the oilfield, while desilter and centrifuge on the second tank. and also the drilling rig would has other different tank as reserve tank,emergency tank, etc.
Mud tanks is an important part in the solids control system. Based on functions, mud tank includes metering tank, circulating tank, chemical tank, aggravating tank, precipitating tank, storing tank, etc.
KOSUN NJ series mud tank often rectangle shape with H shape steel as the main frame, skid mounted after satisfying the strength requirement.
KOSUN NJ series mud tank adopts centralized electric control; heating and heat preservation system applied for tank body in polar regions.KOSUN NJ series mud tanks feature advantages in drilling site: ensuring no mud loss, reducing environmental pollution, lowering labor intensity and satisfying drilling requirements timely through mud mixing. KOSUN can also design and manufacture mud tanks according to customers' specific requirements.
Application of Mud Tank:
As a mud carrier, mud tank is an indispensable part of mud circulation system and it can complete weighting, mixing, solid-liquid separating, degassing and other processes. Mud tank carries the mud circulating between well head and mud pump. The solid phase particles in mud are separated stage by stage through relevant solids control equipment on mud tanks as to make the fluid meet drilling requirements after mixing and weighting system.
