Drilling fluid not only helps the drilling rig into the well in the process of oil & gas drilling, but also can control formation pressures,suspend and release cuttings etc.

Now let's learn more about the function of suspending and releasing cuttings.

Must suspend drill cuttings, weight materials and additives under a wide range of conditions.

Drill cuttings that settle can causes bridges and fill, which can cause stuck-pipe and lost circulation.

Weight material that settles is referred to as sag, this causes a wide variation in the density of well fluid, this more frequently occurs in high angle and hot wells

Drilling Fluid Processing System

High concentrations of drill solids are detrimental to:

Drilling efficiency (it causes increased mud weight and viscosity, which in turn increases maintenance costs and increased dilution)

Rate of Penetration (ROP) (increases horsepower required to circulate)

Mud properties that are suspended must be balanced with properties in cutting removal by solids control equipment

For effective solids control, drill solids must be removed from mud on the 1st circulation from the well. If re-circulated, cuttings break into smaller pieces and are more difficult to remove.

Conduct a test to compare the sand content of mud at flow line and suction pit (to determine whether cuttings are being removed).

By dint of resource sharing and integration of international oil equipment manufacturers and engineering services providers, China Solids Control Company Kosun has built close strategic cooperation with foreign well-known drilling fluid engineering services providers and drilling waste management providers to jointly discuss and develop integrated services, including drilling waste management, drilling fluid supply, drilling fluid additives, oil chemicals, and to provide the most reliable products and the top quality services for oilfields all over the world. The circulation of drilling fluid also indispensably relates to solids control equipment, such as shale shaker, vacuum degasser, desander, desilter, centrifuge etc.
