Abstract
FIELD: oil and gas producing industry. SUBSTANCE: the offered device combines functions of jet pump and hydrodynamic pulsator. The known device for well completion, based on fluid ejection from the formation, is provided with additional appliance which is by special manner hydrodynamically connected with jet apparatus and serves as pressure pulse generator. The device is run in well with packer on tubing. Device when pumping the working fluid into tubing, functions as jet pump. When injecting working fluid or some other chemical reagent the drill string-borehole annulus, it is operated as hydrodynamic pulsator with injection of fluid into formation. EFFECT: higher efficiency.
