Expediency of using high-grade clay powders in drilling wells in the conditions of the North-East and Far North of the USSR.
Abstract
To obtain washing solutions are used clay powders produced by various plants and local lump clays. By the cost of clay material spent on the preparation of 1 m3 of standard solution (with a conditional viscosity of 25 s), as a rule, the wrong conclusion is made about the economic efficiency of local lump clays ...
