FIELD: oil industry.
SUBSTANCE: invention relates to oil production technologies and can be used for gas-dynamic action on formation. Method involves cumulative perforation well interval with formation in well casing string and in mine rock of grouped perforation channels for fluid inflow, subsequent operation of pressure generators and their impact on formation through grouped perforation channels for fluid inflow to form in mine rock of rock individual fractures in direction of each perforation channel. At that, adjacent perforation channels in group are directed in opposite directions. Linear distance between perforation channels in group is different or equal to linear distance between groups of perforation channels.
EFFECT: technical result consists in improvement of efficiency of gas-dynamic action on formation.
