Drilling Mud Shale Shaker to Remove the Cuttings from the Drilling Fluids

Cuttings as the main harmful solids will affect the performance of the drilling fluids during the drilling process. It will make the density, viscocity, abrasiveness, glutinousness, dynamic resistance increased. In addition to this, cuttings is harmful to the oil & gas layer, such as reducing the drilling speed, increasing the rotary torque, leading to well leakage and blowout.

The main function of drilling fluid is well bottom cleaning, cutting carrying, cooling & lubricating the drill and drill pipe, protecting the borehole wall, control and balance the formation pressure, suspend the drilling cuttings and weighting material, remove the cuttings, collecting the stratal data, prevent the oil reservoir damage, transfer the water power and etc.

Main components of the drilling fluids:
1) Water-fresh water, saling water, salt water and saturated salt water,
2) Bentonite, sodium bentonite, Calcium bentonite, Organic dirt or salt resistance etc...
3) Chemical-inorganic, organic, surfactant, polymer, etc.
4) Lightweight oil or crude oil etc...
5) Weighting agent-barite, hematite etc...

Shale shakers http://www.kosungroup.com/products/solids-control-equipment/shale-shaker.html is the first phase mud treatment equipment. Drilling fluids carrying the cuttings to the wellhead. These cuttings required to be clear away on time. Shale shaker is the idea equipment to remove the cuttings among the solids control equipments. If the shale shaker do not work correctly, the subsequent equipment like hydrocyclones and centrifuge cannot work as normal.

Features of the drilling mud shale shaker:
1) Shale shaker is to sieving the liquid and discarding the solid phase particle.
2) Shale shaker is to sieving the solid particle from 0~20μm. Currently the max screen mesh is up to 325 mesh. Seldom use the mesh less than 40 mesh.
3) Due to the characteristic of the well drilling, the shale shaker should be easy to transport, installation, replace the shale shaker screen,...
