METHOD FOR INCREASING EFFICIENCY OF PUMPING AND INTENSIFICATION OF OIL AND GAS PRODUCTION

摘要

1. A method of perforating a well to increase the efficiency of injection and intensification of oil or gas production from an underground formation, the method comprising the following steps: a) loading one or more reactive cumulative charges into the body with charges; c) lowering the body with charges into the wellbore and placing it near the underground formation; c) undermining the cumulative charge, in order to create the first and second explosions, while the first explosion creates one or more perforation tunnels in the adjacent formation, to each trunk of said one or more perforated tunnels surrounded by a crushing zone, and the second explosion causes at least one end of fracturing on at least one perforation tunnel and, in addition, a second explosion pushes detrital material from the tunnel into the barrel skvazhiny.2. The method according to claim 1, including, in addition, the impact on the reservoir, with the aim of stimulating the flow by pumping fluids from the perforation tunnels through the specified fracture into the reservoir. The method according to claim 1, in which the second explosion, in addition, weakens the stress frame, the formation of which was caused by plastic deformation around one or more than one perforation tunnel. The method according to claim 1, in which the second explosion, in addition, reduces the amount of hydraulic power necessary to stimulate the formation of fractures. The method according to claim 1, wherein the resulting tunnel depth after the second explosion is substantially equal to the total penetration depth. The method of claim 1, wherein the second explosion is initiated by the first explosion. The method according to claim 1, in which the depth of free �
