Zusammenfassung:	FIELD: oil and gas industry. ^ SUBSTANCE: method includes forming a depression on bed by gassing column of well liquid due to interaction of acid with alkali metal in well. With decrease of specific weight of well liquid for 20-40% from its basic specific weight well is periodically sealed at mouth. Well is sealed for different time spans. These periods are set by random law to provide for cyclic non-stationary mode of well operation. Such mode is maintained until gassed liquid leaves well and bed fluid debit stabilizes. ^ EFFECT: lower costs, broader functional capabilities, higher efficiency. ^ 7 cl, 1 ex
