Drilling mud is a important part for the drilling work to maintain the wellbore; Cool, lubricate and support the bit and drilling assembly
and so on, most important, remove cuttings from well. Then here it problem, to reuse the drilling mud. Then it is the time for mud circulating system to come here.
In some applications, the mud circulating system is equal to solids control system, but the full mud circulating system in drilling work, contains more. Except for the four phase, five equipments as we know, shale shaker, vacuum degasser, desander and desilter (or mud cleaner), decanter centrifuge. There also include mud pump, electric generator, control panel, chemical reagent treatment unit, and so on.
As you can see in the picture. It is used for the movable drilling rig, and also this system is movable. Usuall solids control equipments can not prevent the loss of the drilling mud. So we also must add chemic to the tanks to add fresh drilling fluids.
Other parts are also very important, centrifugal pump, mud agitator, mud gun.
The main part in the picture :
1. Shale shaker
12. Mud pump
20. Sludge pump
23. Mud agitator
27. Submersible pump
