FIELD: oil production, particularly to stimulate oil extraction under difficult field development conditions, particularly in the case of carbonate formation treatment.
SUBSTANCE: method involves forming new cracks and/or stimulating existent ones in production bed by serially well flushing and performing periodical depressive and repressive actions along with flushing thereof at circulation or outflow stages; isolating interval to be treated with packer; cyclic changing pressure with following injecting working liquid, for instance oil and/or at least one plug of chemical agent, for example of hydrochloric acid. All above operations are performed along with oscillating action of radiator installed in front of production bed interval to be treated.
EFFECT: increased intensity of production bed treatment and extended operational functionality.
