OPERATION WELL JET PLANT AND PUMP-ELECTOR PULSE WELL PLANT FOR REALIZATION OF METHOD Russian patent published in 1999 - IPC

FIELD: jet technology. SUBSTANCE: hydraulic pulse device of jet plant is manufactured in the form of jet-type pumps whose nozzles are at same time throwing nozzles of hydraulic pulse device and their conduits supplying passive medium communicate with space of well beneath hydraulic pump device. The latter has central flow conduit where non-return valve is mounted for removal by flow of fluid. Chemically active medium is pumped into well through central flow conduit made in hydraulic pulse device before supply of active medium into hydraulic pulse device, non-return valve is thrown into string of pipes and used to shut off flow conduit. Chemically active medium is pumped out of well during treatment of zone under packer with active medium under hydraulic pulse cavitation mode. EFFECT: enhanced productivity thanks to increased efficiency of treatment of zone of formation near well. 2 cl, 3 dwg
