| titleOfInvention | Method and device for complex selective action application to oil reservoir |
| abstract | FIELD: oil production industry, particularly to treat well bottomhole zone of reservoir with hard-to-recover oil. n SUBSTANCE: method involves conveying gas-fired heater in reservoir treatment interval, wherein the gas-fired heater operates on liquid chemical reagent so that exothermal decomposition reaction is carried out by bringing chemical reagent in contact with catalyst; initiating chemical reaction by means of catalyst; applying action of high-temperature gas exiting the body orifices to well wall. The gas-fired heater is arranged on flow string between two packers having the same structure and brought into working state by applying gravity load thereto. The tubing string provided with implosion atmospheric pressure air chamber, slurry receiving tank and mechanical action anchor connected to lower packer is used. The lower packer mandrel is sealed with plug. Gas-fired heater has upper container filled with liquid chemical reagent and lower container with liquid catalyst. Lid of upper container is defined by pusher retained by cut off pin. Lower container is defined by lower pusher with needle projection, by bottom partition and cylinder. The lower pusher is fixedly retained with pin and made of elastodeformed material. Upper container is made of chemically destructible material. Upper packer cooperates with the pusher, lower packer interacts with bottom partition. The exothermal reaction is initiated after bottom partition breakage by applying mechanical action of packer mandrel rods during terminal stage of packer bringing into working state. Then purgings are extracted and collected in the implosion chamber and in slurry receiving tank. Lower end of the upper packer is provided with hydraulic relay. n EFFECT: increased efficiency of oil reservoir treatment, simplified structure and increased operational safety. n 3 cl, 2 dwg |
