FIELD: hydrocarbon production, particularly to produce hydrocarbons from highly-viscous underground tar sand or heavy oil deposits.
SUBSTANCE: method involves drilling at least two well pairs including injection and production wells, wherein injection well bottom is located in deposit and production well bottom is arranged in deposit below injection well bottom; preparing said well pairs for further operation; creating permeable zone between injection and production wells; injecting heat-carrier agent in injection well and simultaneously producing hydrocarbons from production well. To increase permeable zone between production and injection wells each well is subjected to hydraulic fracturing operation along with propping agent injection before well bringing into operation.
EFFECT: simplified technology and increased deposit development efficiency.
