Solids Control System

  Hydrocyclones for Desander, Desilter and How to Choose Sand and drilled solids can quickly build up in a drilling fluid system if they are not removed at the right stage. Coarse sand is usually handled by a desander, while finer drilled solids may need a desilter further downstream. Both machines use hydrocyclones, but they are designed for different parts of the solids load. Desanders normally use larger cones for coarse solids, while desilters use smaller cones for finer solids. When selecting hydrocyclones for solids control , the practical questions are simple: What solids need to be removed? How much mud needs to be processed? What are the mud conditions, and what pressure is available at the cyclone inlet? Hydrocyclones for Solids Control The Difference Starts With the Solids A desander is generally installed downstream of the shale shaker. The shaker removes the larger cuttings first, and the desander takes out sand-sized material that remains in the mud. A desilter ...
