FIELD: oil and gas industry.
SUBSTANCE: stimulator of oil formation productivity serving as an additive to the process fluids contains, wt %: an inorganic salt or a mixture of salts of at least 70; nonionic or cationic surfactant with demulsifying and hydrophobizing properties, or a mixture of said surfactants of at least 1; acid is not less than 3; sodium gluconate is not less than 1.
EFFECT: stimulation of oil and gas-bearing formation productivity by combining technological operations with gentle rock processing allowing to increase the phase permeability, hydrophobicize the treated surface, remove capillary-bound water from the pores of the formation, remove sediments and prevent their further formation.
