METHOD FOR HYDRAULIC PULSE IMPLOSION PROCESSING OF WELLS Russian patent published in 2021 - IPC E21B43/25 E21B28/00 E21B43/18 E21B47/00 

FIELD: oil industry.

SUBSTANCE: invention relates to the oil industry, it can be used to restore/increase the productivity of producing and injection wells. The method for hydraulic pulse implosion processing of wells by affecting the bottom-hole zone of a reservoir using the implosion effect includes the descent into the well of an implosion device on pumping and compressor pipes containing an implosion chamber with an expanded part, pressure concentrators, a plunger and a valve. At the same time, the length of the expanded upper part of the implosion chamber exceeds the total length of the plunger, the remote rod and the geophysical device, rigidly connected to each other. The geophysical device with its lower part is rigidly connected to the upper part of the remote rod, and the upper part is rigidly connected to the load-bearing geophysical cable, through which the necessary electricity is supplied to supply it. The length of the lower part of the implosion chamber does not exceed the total length of the plunger and the remote rod.

EFFECT: reduced time of stopping the well, increased efficiency of evaluating the use of implosion processing of wells and increased efficiency of hydraulic pulse implosion processing of wells.
