摘要： The method of wells production rate increase which includes lowering the hydroperforator equipped with hydromonitor nozzles into the well on the pipe string; pumping liquid with abrasive material under pressure into the pipe string and hydroperforator; impacting the well elements and the stratum with the liquid with abrasive material via hydroperforator hydromonitor nozzles. When liquid with abrasive material impacts the well elements and the stratum, pressure is changed in the pipe string delivering the liquid with abrasive material. The difference is that pressure is changed over time so that pressure oscillations always include components with different frequencies, and in doing so, peak values (amplitudes) for at least some pressure oscillation components vary within the time interval Td, where Td≦Tv; Tv being the time of impact of the liquid with abrasive material on the well elements and the stratum via hydroperforator hydromonitor nozzles.

摘要： The invention includes a method of increasing of the well rate of exploitation and recharge wells, comprising a means of decreasing the stress state in the well area by constructing of slot-like discharge key seats, wherein the slot-like key seats have a screw-like shape, wherein preliminary internal rock friction angles ρ are determined for a rock composing a productive strata, and a pitch of the slot key seat screw is selected such that the tangent of the angle of deviation of the slot surface from the φ vertical will be between tg(45−ρ/2)≧tg(φ)≧1/√3, where ρ—is the internal rock friction angle where the key slot is being made.
