Formation solids contained in a mud cleaning system, generally considered to be detrimental to the drilling operation because they produce high plastic viscosity, yield point and gel strengths and build poor-quality filter cakes. They also occupy space that is needed for barite in high-density muds. Drill solids cause excessive wear in the mud pumps and other rig equipment. Solids control is aimed at economically and efficiently removing drill solids. This implies removal as soon as possible after they enter the mud system, while the particles are at their largest size.

Solids removal on the rig is accomplished by the following techniques: shale shakers, desander , desilter, drilling centrifuge. Each device is designed to remove a sufficient quantity and size range of solids. Often these are accomplished using separate devices, but sometimes these processes are combined, as in the case of the mud cleaner, which is a bank of hydrocyclones mounted over a vibrating screen. Another important hybrid device is the cuttings dryer, which is a centrifuge fitted with a cone-shaped shaker. Additional devices can help enhance solids-removal efficiency. For example, a vacuum degasser is sometimes installed (before any centrifugal pumps, typically between the shakers and desanders) to remove entrained air that can security hazard and reduction in mud density.
 

How to improve solids control equipment ?

Improve solids control equipment main aim is to get better property drilling mud. Final function is to decrease or low down the well drilling cost

How to improve solids control equipment ? Drilling mud solids control process request main equipment including shale shaker, desander, desilter, decanter centrifuge. All other equipments in drilling fluid system are assistant ones

The mud equipments improvement should be based on certain well drilling condition and mud conditions. Such as decanting centrifuge process. Sometimes, we need high speed centrifuge to process finer particles but sometimes we need middle speed ones to process larger quantity drilling mud with larger cuttings

The solid control equipment improvement including capacity, cost, style, operation convenience, etc. Anyhow, essential target is decrease drilling cost increase all efficiency
