Mud Solids Control System for Drilling Operations

In oil and gas drilling, a mud solid control system is often used. It can be said that mud solid control is one of the essential equipment in the natural gas and oil drilling process. The five main pieces of equipment in a mud solid control system are, in order: a shale shaker, a degasser, a desander, a desilter, and a centrifuge. All of this equipment is installed on top of the mud tank.

Mud solid control operation procedure

1. The drilling mud is fed from the borehole through the pipeline into the shale shaker buffer box.The shaker can be equipped with a vibrating screen mesh ranging from API 35 to API 120 in order to separate the larger drill cuttings. The liquid portion will pass through the mesh screen and into the sand pit.

2.Mud from the sand pit will overflow into the next compartment.The vacuum degasser will then draw the mud into the degasser, and the treated mud will overflow into the degasser compartment.

3. The desander feed pump will collect the slurry from the degasser compartment and deliver it to the desander cyclone for separation of particles ranging from 47 to 76 microns. The solid portion will fall from the desander nozzle, while the fluid will flow into the desander chamber.

4. The other one will pick up the slurry from the desander chamber and feed it into the desilter cyclone.The solid particles will drop through the desilter nozzles, while the fluid will flow into the desilter chamber.

5、Then, the slurry pump or screw pump draws the slurry from the desludging chamber and transfers it to the decanter centrifuge, where it separates the clean slurry with particle sizes ranging from 2 to 7 microns in the centrifugal chamber.

6、After each tank chamber is de-sludged, the resulting mixture is referred to as net slurry.This slurry can be either suctioned or discharged by the mixing pump into any of the slurry tanks for transfer or new slurry mixing.

7、All clean slurry tanks are equipped with suction lines and valves for slurry pump.
