The general functions of drilling fluids are fairly standardized. Since most drilling operations rely on liquid drilling fluids, we will make them our main concern. The eight basic functions of drilling fluids are listed below.

1. Transportation of cuttings to surface.

2. Suspension of cuttings when circulation is stopped.

3. Control of annular pressure.

4. Lubrication and cooling of the drilling assembly.

5. Provision of wall support.

6. Suspension of drilling assembly and casing.

7. Delivery of hydraulic energy.

8. Provision of a suitable medium for wireline logging.
 

So the performance of drilling fluids is the key in the whole drilling solids control system, we have to keep the drilling fluids performance stable and highly efficient. At this time, the solids control equipment play improtant roles in the drilling fluids circulation system. The decanter centrifuge is the last and most important device in the solids control system.

KOSUN Decanter Centrifuge separates suspension of solid phase with particle diameter not less than 2μm for drilling mud. Ruggedly built for oilfield and industrial services, it is especially effective in environmentally sensitive areas. It delivers high fluid-recovery rates and efficient solids control to significantly reduce the costs of makeup fluids and disposal. The centrifuge is precision balanced for smooth operation over long periods at the speed of 0 to 3900 RPM, generating centrifugal forces up to 3000G’s.

It is mainly used for recycling barite, eliminating small solid, reducing the solid content of drilling fluid, controlling the density and viscosity of drilling fluid, ensuring the performance of drilling fluid, and plays an important role in drilling fluid circulation system.

KOSUN Centrifuge has been developed for many years with continuous improvement and optimization design which is featured by good result of separation and settlement, as well as large treatment capacity, reliable work, longer life, low energy consumption, easy maintenance, smooth operation, lower noise, etc.

KOSUN is a professional in solids control industry, we have been providing the solids control equipment for oilfield for more than 20 years, the products including shale shaker, shale shaker screen, desander, desilter, vacuum degasser, centrifugal pump, mud agitator, drilling fluid mud cleaner, decanter centrifuge, jet mud mixer, mud tank, and complete solids control system, etc.
