FIELD: oil production, particularly oil well bottom treatment to stimulate oil production.
SUBSTANCE: method involves delivering hydroreactive composition in well interval to be treated and filled with well fluid including at least water, wherein the hydroreactive composition is isolated from well fluid and may enter into heterogeneous chemical reaction with at least well fluid water with heat and gaseous product emission; initiating chemical reaction by providing direct contact between hydroreactive composition and well fluid. Hydroreactive composition comprises granular aluminum chloride and organic oil deposit solvent, which does not solve aluminum chloride. Solvent volume is not less than pore space of granules calculated from a given empirical formula.
EFFECT: increased producing ability of well.
