FIELD: oil-and-gas industry.
SUBSTANCE: invention relates to oil industry. Proposed method comprises injection and driving acid agent into productive bed, process holding and extracting the products by depression effects. Note here that said acid agent comprises the following components in wt%: halogen acid - 0.5-5.0, acetic, or citric, or boric, or formic, or chloroacetic, or alkyl benzene sulfonic acid - 8.0-85.0, surfactant - 0.2-5.0, complexing agent - 0.1-1.0, water making the rest. In compliance with second version, prior to injecting said acid agent, bed is subjected to implosion effects.
EFFECT: higher yield and injectivity, intensified fluid influx from productive bed.
