FIELD: oil, gas and coke-chemical industries.
SUBSTANCE: invention relates to oil industry and can be used in development of productive formation by well, which opened multilayer oil deposit with formations of different injectivity. Proposed method of opening productive reservoir comprises casing perforation, packer installation and acid treatment through perforated holes located above packer. Cumulative perforation of the casing string is carried out after installation of a blind packer made in the form of an explosive packer, and acid treatment is combined with thermo-chemical action obtained during combustion of inflammable thermochemical blocks lowered on the cable.
EFFECT: simplified use and broader functionalities at overlapping intervals of less than 5 m due to use of explosive packers, in which there is no WOC, and reduced time for implementation due to use of cable technology.
