FIELD: oil and gas industry. ^ SUBSTANCE: invention refers to oil and gas industry and is designed for thermo-gas-chemical and vibrowave treatment of face zone of oil and gas formation near well and at more distant spaces from well with gaseous combustion products of solid (rocket) fuel for intensifying of oil output. The essence of the invention is as follows: the device includes cylinder powder tube charges, including an igniting charge or igniting charges and load carrying cable with components of device fixture. According to the invention the charges have different diameters of central round channels. At that ratio of lengths of all channels or parts of lengths of these channels not connected with exterior cylinder surfaces of charges by means of transversal through channels and/or slits to diameters of the said channels is (20:40):1. Besides, between the charges and/or in charges themselves there are foreseen passes - circular gaps between charges designed to open after commencement of their burning, and/or transversal through channels in the charges. At that the charges contain a filler-stabiliser of burning, which consists of not more, than 1.5% to total weight of the charges. ^ EFFECT: facilitating upgraded efficiency of thermo-gas-chemical and vibrowave treatment of wells at more simplified design of device. ^ 3 cl, 3 dwg |
