Drilling mud cleaner for solids control

History of mud cleaner

Although US Patent No.3,766,997 covering Mud Cleaner was issued on October 23, 1973 granted to J.K. Heilhecker and L.H. Robinson and assigned to Exxon Production Research Company, it was found invalid and efforts for re-issue was unsuccessful because of the existence of prior art filed at the British Patent Office by a German Inventor in the late 1800s.

Nowadays, 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.

Description of mud cleaner

A mud cleaner is a combination of desanders and/or desilters mounted over a shaker with a fine mesh screen. A mud is fed to the inlet of the hydrocyclone (desander and/or desilter) to separate particles and the underflow passes to the fine screen mesh where in particles larger than barite are discarded and thrown away. 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.

Process flow of mud cleaner

The weighted mud flows to the inlet head section of the desander and/or desilter entering the hydrocyclones for separation of particles. Mud leaving the underflow is further screened with fine mesh to separate larger particles allowing only barite size particles to pass through the screen returning and recovering then the clean mud.

Purpose of mud cleaner

The purpose of the mud cleaner is to remove drilled solids larger than barite. Solids larger than 74-105 micrometres can be removed by the mud cleaner before the viscosity builds up.

Mud Cleaner is the second class and the third class solids control equipment which is the newest type to treat the drilling fluid. OGEM drilling mud cleaners are combined from Desander, Desilter and an Underflow Screen, at the same time

Mud cleaner has the higher cleaning function compared with separated desander and desilter. In addition to the reasonable design process, it equals another shale shaker. OGEM mud cleaner structure is compact, it occupies small space and the function is powerful. Mud cleaner is the ideal device of the second class and the third class solid control to treat the drilling mud.

 

Drilling mud Cleaners for drilling fluids solids control:

 Drilling mud cleaner is also called Desander and Desilter assembly, which is the combination of desander, desilter and an underflow screen. 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.
