FIELD: oil and gas industry.
SUBSTANCE: according to the method the connection to distant formation zone is established so that its coverage by draining is increased, and complications caused by rock caving after perforation are prevented. Perforation is performed downwards with increased perforation density with cumulative charges of lower power where there is not any nearest water-bearing formation or water-oil contact. After perforation the chlorhydric acid treatment of open hole is performed. At that, increase in formation pressure and preservation of water content on the same level is accepted as result of the performed treatment.
EFFECT: higher well productivity.
