Annotation:

The article provides a variant of solution to the problem of carrying out an expensive technological operation of a multi-stage hydraulic fracturing. The authors of the article, within the framework of the import substitution program, propose using a technology and a technical device for carrying out a multistage hydraulic fracturing. Equipping the production casing string by pipes with a weakened cross-section, equipped with a brittle bitumen bandage and a wear-resistant material casing, allows creating a large number of hydraulic fracturing intervals in one approach to the well using a tubing assembly with a selective packer.
