The quality of drilling fluids purification is the key in drilling, how to handle the solids well in that is a noteworthy issue, the mechanical treatment for drilling fluids is the most used way in drilling.

Mechanical Treatment of Drilling Fluids

This is the method of mechanically removing solids using shale shakers or hydrocyclone devices such as; desander and desilter. Each piece of equipment is general limited to the following range of particle removal:

Standard shale shaker-440 μm or larger (also referred to as the scalping shaker)

Fine screen shaker-74 μm or larger

Desander-100 μm & larger

Desilter-15 μm & larger
 

Correctly implemented each piece of mechanical solids control equipment is effective within a certain particle size range. Utilizing all or a combination of the above equipment throughout your boring program will produce maximum benefits and result in a cost effective means of controlling your solids within an affordable budget.

Mechanical Separation Basics

Mechanical separation equipment employs mass differences, size differences or a combination of both to selectively reject undesirable solids and retain desirable drilling fluids. The desanders and desilters utilize centrifuge force and mass difference between the solids density and liquid density for solids removal. The shale shakers employ a vibrating screen of various micron-sized differences.

A standard rig shaker or fine screen shaker is vital to the solids control and should process 100% of the mud returning from the starting pit before allowing this mud to be processed by any of the down stream equipment you may utilize in your solids control system.

With so important effect for drilling fluids, we can't working in oil and gas drilling without solids control equipment. KOSUN is a professional manufacturer of those devices, such as shale shaker, decanter centrifuge, mud cleaner and other equipment, like mud pumps, mud guns and mud tanks.
