METHOD FOR COMBINED EFFECT ON FORMATIONS CONTAINING HYDROCARBONS AND/OR SOLID ORGANIC SUBSTANCES AND DEVICE FOR IMPLEMENTING SAID METHOD Russian patent published in 2016 - IPC E21B43/24 

FIELD: oil and gas industry.

SUBSTANCE: group of inventions relates to oil and gas industry. Method for action on productive formations containing hydrocarbons and/or solid organic substance involves formation of working agent represented by water, which is mainly in supercritical state (SC-water), and subsequent spontaneous injecting working agent in productive formations. Working agent is formed on surface of well in ground generator of SC-water containing unit for enrichment of formed SC-water with exothermal oxidation catalyst. Working agent enriched with said catalyst is supplied via product with insulation in well and/or downhole zone of exothermic oxidation reactions in SC-water, wherein well and/or downhole fed by separate product lines reactants - organic compounds and organic compounds oxidising agent, providing additional heating and additional pressure increase above pre-formed working fluid due to exothermic oxidation reactions in SC-water to produce carbon dioxide (CO₂), in a supercritical state, then finally formed spontaneous working agent is injected into formation.

EFFECT: technical result of intensification of production of deep natural bitumen and heavy oil and oil low-permeable rocks, as well as for in-bed generation synthetic hydrocarbons from solid organic substance - kerogen.
