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.

Предлагаемое устройство совмещает функции струйного насоса и гидродинамического пульсатора. Известное ранее устройство для освоения скважин, основанное на эжекции жидкости из пласта, снабжено дополнительным устройством, которое специальным образом гидродинамически связано со струйным аппаратом и является генератором импульсов давления. Устройство спускается в скважину с пакером на насосно-компрессорных трубах. При закачке рабочей жидкости в насосно-компрессорные трубы устройство работает как струйный насос. При закачке рабочей жидкости или какого-либо химреагента в затрубное пространство устройство работает как гидродинамический пульсатор с закачкой жидкости в пласт.

The proposed device combines the functions of a jet pump and a hydrodynamic pulsator. The previously known device for well development, based on the ejection of fluid from the reservoir, is equipped with an additional device, which is in a special way hydrodynamically connected to the jet apparatus and is a pressure pulse generator. The device descends into the well with a packer on tubing. When pumping the working fluid into the tubing, the device works like a jet pump. When pumping a working fluid or any chemical into the annulus, the device works as a hydrodynamic pulsator with pumping fluid into the reservoir.
