Drilling fluids solids control equipment in the oilfield

Drilling mud solids control equipment (solids control for short) are drilling equipment to control or separate the undesirable and even harmful solids mixed in drilling fluids. The separation of harmful solids from drilling fluids will contributes to better mud property and meet the increased demand on drilling efficiency by the scientific application and arrangement of solids control equipment.To form resonable and effective workflow of solids contrtol equipment is the key to achieve solidsc control goal.
The new type drilling mud solids control system adopts five stage of solids control,following is the proper workflow of solids control technology.
The first solids control equipment mainly remove the large particles.The drilling fluids,pumped out of drilling hole containing large cuttings,will flow into shale shaker through connecting pipes.The removal of particles with diameter above 74 microns in shale shaker marks the achievement of first stage of solids control.
The second stage of solids control equipment is vacuum degasser used to remove harmful gas gathered in drilling fluids during normal operation.The vacuum degasser is the dedicated degasser equipment specialized in immediate and effective removal of undesirable gas which will change mud density and exert security hazard such as blowout and well fall.

The treated solids particles will be flow into the third solids control equipment where the sand with diameter from 44 to 74 microns will be removed. Desander plays its parts in this stage.
The fouth solids control equipment is desilter.In this case,the solids particles with diameter ranging from 15 to 44 microns are to be separated from the rest and will go through further processing in decanter centrifuge.It is worth of being noticed that the desander and desilter can be combined together to form a more effective solids control equipment named mud cleaner.
The fifth or the final solids control equipment is decanter centrifuge.After treated by the metioned solids control equipment,the drilling fluids contains fine solids( whith diameter from 2 to 15 microns)which have been failed removed will be treated by decanter centrifuge.With a high centrifugal force and high end technology,Decanter centrifuge is highly effective in the separation of fine particlels.
The mentioned five solids control equipment is mainly used in complex and demanding drilling condition, however,the drillers can select one or part of the metioned equipment depending the practic drilling operation.
