The common problems of oilfield drilling desilter

Oilfield drilling desilter is the third stage of oilfield solids control equipment. In oilfield solids control system,the solids with diameter ranging from 15 to 44 μm are to be separated from the rest,which will go through further processing.The Oilfield drilling desilter is the third stage equipment in the whole drilling mud system, at the same time, it is an important device, too. Let’s see some common problems and solutions for that .

Common Problems

(1) Repeated plugging of Apex in all cones.

(2) One or more cones plugging while others are working normally.

(3) Cones are loosing whole mud in stream.

(4) Solids content in cone overflow continues to increase over time.

(5) The underflow discharge is very dry.

(6) Hydrocyclones leak between the cone nut and body, but no fluid is coming out of the bottom.

Possible Cause

(1) Too small of underflow opening.

(2) Plugged at feed inlet or outlet.

(3) Backflow from overflow manifold, or centrifugal pump impeller worn out or too small,

(4) Drilling through hydratable clays will cause increased viscosity.

(5) Strong vacuum in manifold discharge line.

(6) The apex cone nut is tightened too much which does not allow fluid or solids to exit the hydrocyclones.
