To improve the technological processes of drilling in difficult geological and technical conditions by using foam flushing systems (FFS) requires compressed gas of medium or high pressure. A new direction in the search for effective ways of obtaining FPS was the use for these purposes of compressor-compression devices (CCD), implemented on the bases of drilling pumps.

With the existing methods of drilling, the growth of labor productivity is largely constrained due to the large amount of time spent on performing round-trip operations …

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 ...
