The role of bariteEffect of barite in drilling fluid
Sometimes the mud weight does not balance with the underground oil or air pressure, which will cause a blowout accident. The underground mud must be increased when the underground pressure is higher,
Drilling fluid weighting agent: in some oil and gas wells drilling, the commonly used drilling mud, clay proportion is about 25, the proportion of water is 1, so the proportion of mud is low,
Effective measures to increase the proportion of mud mud is added into the barite. Drilling mud with barite fineness to generally reached more than 325 mesh, such as barite insufficient fineness is prone to precipitation. Drilling mud with barite requirement is more than 4.2, BaSO4 content of not less than 95%, the soluble salts of less than 1%.
