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.


We are an exporter of drilling mud cleaner for companies all around the world. Our  company is Quality Management System ISO 9001-2008 certified. OGEM Solids Control operates waste mud management international sales, service, manufacturing, distribution service.

Buy drilling mud cleaners from China manufacturer, good quality, best price, OGEM is your best choice of drilling mud cleaner.

Drilling_Fluid material

 What can fluids system do?

The drilling fluids system is also called drilling mud system. For oil drilling, the main function is solids control or separate out drilling cuttings, mix drilling fluid, storage clean mud. Finally make drilling fluid circulated. After system finish purification work the drilling fluid will be clean and high property

Through whole drilling fluids system, we can eliminate invaded gas or natural gas by poor boy degasser. Subsequently, shale shaker will separate particles larger than 100 microns. Usually we’ll use vacuum degasser/gas buster to get rid of less interfused air behind shaker.

Oilfield drilling fluid centrifuge

As per well drilling deeper and deeper the fluid will correspondingly change property.  The hydrocyclone separator will separate finer solid out of drilling mud. Or we combine desander cone, desilter cone, and shaker to be mud cleaner get rid of particles over 12 microns.

In whole drilling fluids system, we request decanter centrifuge for 4th phase solids control. Generally speaking, after centrifuge processing, the drilling mud will be called clean drilling fluid.


As we said just now, the drilling fluids system will provide mix and storage application. Here is coming mud mixing pump, mud agitator, and jet mud gun. For mud mixing we need mixing hopper pump. On storage tank, mud agitator and jet mud gun are mixing equipment. They will be operated together mix drilling fluid keep it suspending.

The above is basic information of drilling fluids system working principle, functions, and whole process. So here come results, drilling fluids system will make drilling fluid purified or recycled. Help oilfield drilling perform better, decrease drilling cost, etc.

Hydrocyclone Desander for OGEM Solids Control

Introduction of desander

Desanders and desilters are drilling rig equipment with a set of hydrocyclones that separates sand and silt from the drilling fluid.

Desander is installed after shakers and degasser but before desilter. Desander removes those abrassive solids from the drilling mud which cannot be removed by shakers. Desilting is employed in dams and lakes.

A centrifugal pump is used to pump drilling fluid through the set of hydrocyclones.


Desander for solids control

Desander has no moving parts. The larger the internal diameter of the desander is, the greater the amount of drilling fluids it is able to process and the larger the size of the solids removed.

Desander (10 inches (250 mm) cone) are able to remove 50% of solids within the 40-50 μm (micrometre) range at a flow rate of 500 US gallons per minute (32 L/s), while desilter (4 inches (100 mm) Cone) are able to remove 50% of solids within the 15-20 μm range at a flow rate of 60 US gallons per minute (3.8 L/s). Micro fine separators are able to remove 50% of solids within the 10-15 μm range at a flow rate of 15 US gallons per minute (0.95 L/s).

旋转 DSCI0087_旋转_副本

Desander is typically positioned next-to-last in the arrangement of solids control equipment, with decanter centrifuge as the subsequent processing unit. Desander is preceded by gas busters, gumbo removal equipment (if utilized), shale shaker, mud cleaner (if utilized) and vacuum degasser. Desander is widely used in oilfield drilling.


OGEM CSQ Series Desander

CSQ series desander is the second class and the third class solid control equipment to treat the drilling fluid. According to the size of the cone diameter, it is divided into Desander and Desilter.

Usually the cone diameter is more than 6″is called Desander, and used as the second-control equipment in drilling operation. We commonly used 8 “and 10″ cones desander to separate solid-phase particle size 47-76μm in the drilling fluids.


Any need for desander, please feel free to contact us and we’ll do our utmost to serve you.


Single screw pump suppliers from China

 Introduction and Definition

screw pump is a positive displacement pump that use one or several screws to move fluids or solids along the screw(s) axis. In its simplest form (the Archimedes’ screw pump), a single screw rotates in a cylindrical cavity, thereby moving the material along the screw’s spindle.

This ancient construction is still used in many low-tech applications, such as irrigation systems and in agricultural machinery for transporting grain and other solids.


Development of Screw pump

Development of the screw pump has led to a variety of multiple-axis technologies where carefully crafted screws rotate in opposite directions or remains stationary within a cavity. The cavity can be profiled, thereby creating cavities where the pumped material is “trapped”.

In offshore and marine installations, a three spindle screw pump is often used to pump high pressure viscous fluids. Three screws drive the pumped liquid forth in a closed chamber. As the screws rotate in opposite directions, the pumped liquid moves along the screws spindles.

Three-Spindle screw pumps are used for transport of viscous fluids with lubricating properties. They are suited for a variety of applications such as fuel-injection, oil burners, boosting, hydraulics, fuel, lubrication, circulating, feed and so on.


Difference between other pumps

Compared to centrifugal pumps, positive displacements (PD) pumps have several advantages. The pumped fluid is moving axially without turbulence which eliminates foaming that would otherwise occur in viscous fluids.

They are also able to pump fluids of higher viscosity without losing flow rate. Also, changes in the pressure difference have little impact on PD pumps compared to centrifugal pumps.


OGEM Benefits

The single screw pump is made from stainless steel, we OGEM can produce it with complete stainless steel body by customers’ requirements. AJL series screw pump is with less accessories, compact structure, small space, easy maintenance, rotor and stator are wear parts of this pump, it is convenient to be replaced.
