Abstract

The invention provides a desander. The desander comprises a distributor and two or more cyclones, wherein the distributor is a container arranged vertically; the container is divided into an upper part and a lower part by use of a separator arranged in the container; a feeding hole is formed in the lower part of the distributor, while a discharge hole is formed in the upper part of the distributor; the inlets of the two or more cyclones are communicated with the lower part of the distributor; the overflow ports of the two or more cyclones are communicated with the upper part of the distributor. The desander is capable of uniformly distributing mud.

Description

technical field [0001] The invention relates to the field of oil exploitation, in particular to a desander. Background technique [0002] During the drilling process, the solid phase control of drilling fluid is to remove the harmful solid phase in the drilling fluid and preserve the useful solid phase to meet the requirements of the drilling process for the performance of the drilling fluid. The commonly used methods include dilution method, substitution method, mechanical method and chemical method. The mechanical method generally uses equipment such as vibrating screens, sand removers, desilters and centrifuges. The distributor of the existing desander is arranged horizontally, and there is a problem of uneven mud distribution. Contents of the invention [0003] The problem to be solved by the present invention is to provide a desander which distributes mud evenly. [0004] In order to solve the above technical problems, the technical solution adopted by the present i...
