FIELD: oil and gas industry.
SUBSTANCE: assembly includes shank, packer, return valve, hydraulic jet pump. According to invention the assembly additionally includes second hydraulic jet pump and pressure pulse generator, the latter of which is mounted at the interval between hydraulic jet pumps and is capable of operation under the influence of working fluid pumped by tubing string. Note that pressure pulse generator has turbine stages - stators with holes and rotors with gates capable of regular closing of holes in stators that are fixed against turning relatively each other, like rotors, for sudden changing of stream velocity through hydraulic jet pumps.
EFFECT: increase of efficiency of used assemblies with hydraulic jet pumps in the course of development of wells with low-permeable beds at viscous oil production.
