Composition and performance of oilfield drilling fluids desander
Another name for oilfield drilling fluids desander is mud cleaner. The secondary solids control equipment is mainly used in the drilling mud circulation process, which is generally a combination of two de-sanding cyclones underflow vibrating screens. Its compact structure, small footprint, and powerful functions make it an ideal processing equipment for drilling mud for secondary solid phase control.
The oilfield drilling fluids desander consists of a cyclone, a drip trough, an underflow vibrating screen, a support and a base, and a vibrating motor.
The performance of oilfield drilling fluids desander mainly has the following points:
A control butterfly valve is installed between the main inlet pipe and the outlet pipe of the oilfield drilling fluids desander, the base is equipped with a chute, the vibrating screen is located on the chute, and the cyclone is equipped with an automatic sand control device and an underflow orifice adjustment device.
Applicable to the new type of compact structure, convenient use, easy maintenance, reliable work, can quickly remove harmful solid phases in drilling fluid, improve drilling fluid performance, and meet the requirements of the new high-pressure jet drilling process.
The cyclone group of oilfield drilling fluids desander is composed of 2 high wear-resistant polyurethane desander cyclones arranged in combination. The diameter of the overflow pipe and the feeding pipe is larger, and the cone angle of the cone is smaller; thus, the slurry pump for sand removal The pressure of 0.21-0.40mpa is formed by the mud-removing slurry supply pump to achieve the effect of swirling flow.
The oilfield drilling fluids desander mechanism uses a tiltable metal tank fixed with the central axis to control the flow direction of the mortar; the circular arrangement of cyclones is used in conjunction with the rectangular recovery vibrating screen.
