FIELD: oil and gas industry.
SUBSTANCE: invention relates to oil and gas industry, in particular, to drilling muds used on completion of wells, and to process fluids used in underground well repair. Solution additionally contains marble chips of 0.2 to 2 mm fraction, at that Yalan-E-2 emulsifier grade B2 is used, at specified ratio of components.
EFFECT: high thermal stability and sedimentation resistance of the blocking hydrophobic-emulsion solution with possibility of controlling its density and rheological properties, maintaining filtration-capacitance characteristics of bottom-hole formation zone and preventing absorption of killing fluid.
