FIELD: oil and gas industry.
SUBSTANCE: jet assembly is designed for implementation in oil extracting industry, particularly in the equipment for well bottomhole zone cleanup by means of chemical action at the bottomhole zone with the following pumping out of mudding. The assembly consists of a case, a jet pump, a system of valves and sliding valves installed in the case of the assembly and designed to switch fluid flows at different operation modes.
EFFECT: upgraded reliability of a jet assembly for chemical treatment of a bottomhole zone.
