The Purification Process of Drilling Fluid in the System

The Purification Process of Drilling Fluid in the System
1) Primary Purification
    Primary purification is the drilling fluid treatment through Shale shaker. The configured drilling fluid was taken into bottom of drilling well, then turn back to the ground with drilling cuttings. Through the drilling pumps then come into the shale shaker. The shale shaker separate the bigger solids out from the drilling fluid.

2). The secondary purification
     When the drilling fluid was soaked in gas, using the Vacuum degasser can remove the gas in the drilling fluid. So thus can recover the drilling fluid density, stable drilling fluid viscosity.

3). Tertiary purification
     After the secondary purification, the drilling fluid enters the Desander by the power of centrifugal pump. Through the desander's hydrocyclones, the solids size bigger than 40-60 micron meters were separated out.

4). The level fourth purification
     After the tertiary purification, the drilling fluid enters the Desilter by centrifugal pump. Through the desilter's hydrocyclones, the solids size bigger than 15-40 micron meters were separated out.

5). The fifth level purification
     The drilling fluid after the fourth level come into the Decanter Centrifuge by the power of Screw pump. The decanter centrifuge can separate the solids size 5-15 micron meters out.
