FIELD: oil-and-gas industry. ^ SUBSTANCE: invention relates to oil-and-gas production, particularly, to methods of producing high-viscosity oil and bitumen from underground accumulations with the help of heat. Proposed method comprises developing accumulation by, at least, one pair of wells including fill-in well acting on top part of producing formation and extracting well exploiting producing formation bottom, carrying out hydraulic fracture with injection of proppant in every well, injecting heat carrier into fill-in well and simultaneous hydrocarbon extraction from appropriate well. Note here that in carrying out hydraulic fracture, proppant mixed with granulated magnesium at the ration of 5:1 to 2:1. After injection of proppant-granulated magnesium mix, hydrochloric acid is injected in amount sufficient for complete reaction of granulated magnesium. ^ EFFECT: higher efficiency of oil and bitumen production. |
