Characteristics and working principle of desander in mud drilling
The desander in mud drilling and the drilling fluid desilter can be made as independent equipment or combined into a mud cleaner.
The product features of the desander in mud drilling are that the material of desander in mud drilling is high wear-resistant polyurethane, which has a longer service life. The connection method is clamp type connection, which is convenient for installation and disassembly. Compact structure, small footprint, flexible handling, etc. According to different processing capacity, 1 or 2 or 3 or 4 or 5 Desilters can be flexibly selected. The size and quantity of desander in mud drilling can be flexibly configured to better meet the customized requirements of customers.
How desander in mud drilling works:
The drilling mud is transported to the desilting cyclone in the desander in mud drilling silo through the sand pump. Under the pressure of the sand pump and the impact force of the mud flow, the drilling mud forms a vortex in the cyclone and solids in the drilling fluid are formed. Under the action of centrifugal force and gravity, it settles to the bottom of the cyclone, and finally sprays out through the drip nozzle. The solid particles are further screened and filtered in an underflow screen. The lighter, clean liquid will flow directly into the desilting bin through the discharge line of the cyclone group. The liquid in the desilting bin will be continuously supplied to the centrifuge by the centrifuge pump for the fourth-stage solid control treatment.
Scope of application of desander in mud drilling:
Secondary solid control treatment for mud and liquid to be treated in onshore and offshore oil and gas drilling / coalbed methane excavation / trenchless directional crossing / piling engineering / waste sewage, mud treatment and other projects. In short, it is the desliming treatment of mud and solid-liquid mixture suitable for various environments.
