Wellbot zone development method

Abstract

The invention relates to the oil extraction industry, in particular to increasing the permeability of the bottom zone of production wells by affecting it with a microemulsion and intensifying fluid production from the formation to the well. In the claimed method of developing a wellbore zone, which consists in injecting a microemulsion consisting of a surfactant, a hydrocarbon fluid, hydrochloric acid and a stabilizer into the wellbore zone, according to the invention, a microemulsion containing sulfonol as a surfactant, kerosene as a hydrocarbon fluid and technical lecithin as a stabilizer in the following ratio of components is injected into the wellbore zone (in % by mass): Technical lecithin 10.0-12.0 Sulfonol 1.0-1.2 Hydrochloric acid 10.0-12.0 Kerosene 25.0-30.0 Water residue
