METHOD FOR TREATING BOTTOM-HOLE ZONE OF WELL Russian patent published in 1999 - IPC

Abstract RU 2124631 C1

FIELD: oil production industry. SUBSTANCE: according to method of treatment, specific number of perforations in well is increased to 24-30 per one linear meter, then powder charge is burnt in bottom hole of well. String of pump-compressor pipes is lowered into well together with jet-type pump and packer, and acid solution is introduced under pressure into oil well when packer is not applied. Technological delay is undertaken so as to ensure reaction of acid solution. Packer is applied and short-time depressive treatment is effected to initiate inflow of fluids. Application of aforesaid method enhances efficiency of treating bottom-hole zone of well. EFFECT: higher efficiency.
