Importance of lubricating additives in diamond drilling
Authors:
Abstract
Lubricating and cooling liquids used in drilling practice can be divided into aqueous solutions of electrolytes (NaCl, CaC1g, etc.); solutions of surface-active substances - surfactants (soap and oil, sulfanol, 0P-7, etc.) and emulsion solutions of surfactants (soap and oil, sulfanol, 0P-7, etc.). ) and emulsion solutions obtained from special euilsols (B, SNAD-1, ZL-4, etc.), as well as from various oils introduced into the solution together with emulsifying additives and special additives. Emulsion solutions can be of the oil-in-water or water-in-oil type ...
