发明名称 Method and system for increasing well rate using well-capital-string perforation
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 T<SUB>d</SUB>, where T<SUB>d</SUB><=T<SUB>v</SUB>; T<SUB>v </SUB>being the time of impact of the liquid with abrasive material on the well elements and the stratum via hydroperforator hydromonitor nozzles.
