FIELD: oil and gas industry.
SUBSTANCE: invention relates to oil industry, in particular to process fluids for intensification of oil production from wells exploiting fractured-cavernous reservoirs-reservoirs. Hydrophobic emulsion for treatment of oil formations, containing emulsifier based on hydrocarbon solution of alkanolamine ethers and amides of oleic acid and mineralized formation water, emulsifier contains emulsifier ITPS-013 G at the following ratio of components, wt%: emulsifier ITPS-013G 8–10, mineralized water 90–92.
EFFECT: high viscosity and structural-mechanical properties of the hydrophobic emulsion, which provide reliable plugging of the fracture-cavernous intervals of the collector and deviation of acid into oil-saturated zones of the formation, as well as reduction of material and energy costs due to reduction of components of hydrophobic emulsion.
