Mud pit with solids control equipment


1. What solids control technique ever used?

In the late 19th century when open earthen pits were used to separate the cuttings from the borehole. This was accomplished by a series of weirs and settling pits that allowed the solids to naturally settle out by using gravity. The clean mud then flowed into a suction pit to be re-pumped down the hole. This was the first solids control technique ever used.

2. what drilling mud processing equipments we are using now ?

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.
