Zusammenfassung:A plugging tool includes an elongated inner housing allowing a first fluid to flow through a hollow interior of the inner housing, a retractable plunger positioned within the inner housing and operable to obstruct the flow of the first fluid into a discharge chamber and resume the flow of the first fluid into the discharge chamber based on a pressure exerted by the first fluid on the retractable plunger, and at least one pressure release valve (PRV) operable to open and release at least a portion of the first fluid from the inner housing based on a pressure exerted by the first fluid on the at least one PRV, wherein operation of the retractable plunger and the at least one PRV generates pulses of the first fluid used to deposit a sealing plug at a target interval of a wellbore.
