The invention relates to oil-and-gas producing industry and can be used for increase of effectiveness of development of new wells, increase of productivity of operated ones. Method for increase of length of perforation channels of productive stratum includes delivery of hydro-reacting composition, buffer liquid and water to perforation zone and treatment of productive stratum with high-temperature chemically active mix under pressure. Working components of mix – hydro-reacting composition and water are brought to perforation zone of productive stratum with separated volumes, with layer-by-layer pressing in with formed in tubing string piston pressure. At that hydro-reacting composition is delivered in volume of inert buffer liquid, as that one uses chlorine-derivatives of carbon, for instance tetrachlorethane, at volumetric ratio hydro-reacting composition : buffer = 1: (0.6-2.0), respectively. |
