Beschreibung
Zusammenfassung:	FIELD: oil industry, particularly development of injection or producing well. ^ SUBSTANCE: method involves performing dynamic fluid discharge from well in the following mode: well pressure increase up to well injectivity beginning; fluid discharge from well and repeating above operations. Working fluid is preliminarily injected in pulsed regime in the following mode: well pressure increase up to well injectivity beginning, holding working fluid at rest up to pressure reduction. Pulsed working fluid injection and holding at rest are repeated up to working agent bursting in well bottom zone through contaminants and mud deposits. Dynamic fluid discharge operations are to carry out contaminants and mud deposits from well bottom zone into well with working fluid. ^ EFFECT: increased efficiency. ^ 1 ex
