The specific application of the drilling mud settling centrifuge in the drilling process

Drilling mud settling centrifuge is a special equipment for solid-liquid separation designed for the characteristics of oil drilling fluid. Through it, various processes such as feeding, centrifugal settling and discharging can be completed under full-speed operation, thereby achieving a series of corresponding operation purposes.

 

After practice, it is found that the drilling mud settling centrifuge has played an important role in recovering heavy spar, removing fine solids, reducing the solid content of drilling fluid, controlling the density and viscosity of drilling fluid, ensuring the performance of drilling fluid, and performing fast drilling.

 

The drilling mud settling centrifuge realizes the separation of drilling suspension by using the centrifugal settling principle. In use, suspension enters the rotary drum from the feed pipe through a liquid outlet hole in the screw push, solid particles are pushed to the inner wall of the rotary drum under the action of centrifugal force, and the solid particles are pushed to the slag discharge port at the small end of the rotary drum through blades on the screw push. The liquid phase overflows through the overflow hole at the large end of the rotating drum, so as to achieve the purpose of continuous separation through the continuous circulation.

 

In addition to the suspension separation, drilling mud sedimentation centrifuge has a quite good sand removal effect. That 's because the equipment settlement parameters and feeding mode are optimized. The vibration and noise of the whole centrifuge are reduced to a very low level by improving the machining precision and dynamic balance precision of the rotating part of the drilling mud settling centrifuge.

 

Because the key component—spiral propeller of the drilling mud sedimentation centrifuge is made of thick steel plate fine workmanship, and also on its surface coated with tungsten carbide, which greatly extends the service life of the machine and parts. The same is true of its main bearings, differentials and other components, which enable the drilling mud settling centrifuge to adapt to the harsh conditions of the drilling site.
