Drilling fluid desander and desilter integrated mud cleaner, or integrated cleaner for short, is used for separating the solid-phase particles in the drilling fluid after treated by the shale shaker.
Mud cleaners were developed in the early 1970s to remove fine drilled solids from weighted mud without excessive loss of barite and fluid. They have also proved valuable tools in closed systems and other applications. These devices use a combination of desilter hydrocyclones and very fine mesh vibrating screens (120-400 mesh) to remove fine drilled solids while returning valuable mud additives and liquids back to the active mud system.
Now, in most drilling operations, a mud cleaner is installed in its mud systems. It is usually located in a mud tank in the same location as with the desilters. Mud cleaner used in oilfield means the equipment processing drilling mud. It is combined with desander cone and desilter cone as well as bottom shaker. It is called 2nd and 3rd phase solids control equipments. The purpose of the mud cleaner is to remove drilled solids larger than barite. Solids larger than 74-105 micrometers can be removed by the mud cleaner before the viscosity builds up.
Drilling mud cleaner is also called Desander and Desilter assembly. Namely, mud cleaners consist of a two-stage separation process using a combination of hydrocyclones mounted over a shale shaker to operate as a single unit. Designed to handle the entire circulating volume, Drilling cuttings cleaners are effective on both weighted and unweighted drilling-fluid systems in removing and drying solids while retaining the expensive liquid. The hydrocyclones (desanders and desilters) make the primary separation with underflow directed onto the shaker’s vibrating screen. Used correctly, the drilling mud cleaner lower both drilling-fluid and disposal costs.
In oilfield solids control, drilling mud cleaners are very efficient for oil gas well drilling mud purification system. Mud Cleaners are one of the important equipments for solids liquid separation system.
