Patent ID: 7568525

Claim:
A method of increasing well production rate, comprising: lowering a hydroperforator equipped with hydromonitor nozzles into a well on a pipe string; pumping liquid with abrasive material into the pipe string and hydroperforator under an influence of a time varying pressure, impacting thereby well elements and a stratum with the liquid with abrasive material via the hydroperforator hydromonitor nozzles; wherein the time varying pressure includes multiple harmonic frequency components; wherein a peak value of at least one harmonic frequency component of the time varying pressure changes within the time interval of impact of the liquid with the abrasive material on the well elements and the stratum via the hydroperforator hydromonitor nozzles; and wherein prior to pumping the liquid with abrasive materials into the pipe string and hydroperforator, the well is flushed to its bottom by pressure pumping of a well flushing solution into the pipe string, hydroperforator and a well annular space under an influence of a time varying pressure, wherein the flushing solution includes at least one chemical.
