METHOD OF DEVELOPMENT OF OIL WELL AFTER CARRYING OUT THE HCT Russian patent published in 2020 - IPC F04F5/54 

FIELD: jet equipment.

SUBSTANCE: method for reduction of development time consists in lowering the equipment layout into the well on the tubing string or flexible tubing string. Ejector pump is installed in axial channel of housing on seat between inner wall of housing and limiter, and packer is fixed. Then, acid solution is injected into the tubing string under excessive pressure. Solution, through radial channels of the support and the vertical channel of the hydraulic distributor, under excessive pressure, squeezes the spring-loaded sphere downwards and comes out onto the face through channels. Further, a working agent is fed to the pump nozzle and drainage is performed. Pumped liquid passes through the vertical channels of the flow control valve, wherein the remaining unreacted acid is neutralized when passing through the filter with magnesium.

EFFECT: higher efficiency of the installation when processing the productive stratum.
