drilling fluid in -- centrifuge process

Thursday, 13th November 2014 at 12am - 12am Monday, 30th November 2015

This event is in the past.

The centrifuge process the drilling fluid by control the feeding rate. Before the centrifuge process the drilling fluid, other process machines like shale shaker, desander, desilter, (or mud cleaner combine shale shaker, desander and desilter in one)  place in front  in order to rid of the bigger solid debris, the centrifuge remove the very small size of debris. The shale shaker and hydrocyclone on desander and desilter can’t remove the most part of debris. Adding centrifuge can process fluid further by remove much smaller debris to achieve much cleaner drilling fluid.

centrifuge process

Drilling fluid enter into the hollow shaft in the spiral conveyor by the feeding tubes, then flow into bowl. Because of the high speed rotating of the bowl , to drive the entered drilling fluid rotating together, the solid debris in the drilling fluid is thrown the wall of the bowl, the drilling fluid expel from the screw conveyor pushing to the discharge hole of the small port. The choice of centrifuge by the debris size of separation solid phase, the bowl diameter of centrifuge, the highest speed and the separation factors influence, the drilling site commonly used the solid and liquid density difference, as the separation basic of the settlement centrifuge, mainly clear the solid phase substance in the drilling fluid, is the last level of drilling fluid solid control equipment.

 

How remove the solid in drilling fluid of the oil centrifuge alone?
Drilling fluid mud is into high rotation speed, create high g-force. Then solid and drilling fluid mud is separated.


How work of the oil centrifuge?
Through the feed pipe enter into the conveyor, then mud through the feed port enter into conveyor belt and exit the central, with the high rotation speed of bowl, drilling fluid mud exposure the high force, led to the liquid and solid separation.
