HEATING OF HYDROCARBON-CONTAINING BEDS IN PHASED PROCESS OF LINEAR DISPLACEMENT Russian patent published in 2012 - IPC E21B43/24 

FIELD: oil and gas industry.

SUBSTANCE: according to the method, heat is supplied to the first section of the bed with the help of one or more first heaters arranged in the specified first section, the first hydrocarbons are heated in the first section so that at least some of the first hydrocarbons become movable, at least some of the specified first hydrocarbons are produced via a producing well arranged in the second section of the bed. At the same time the specified second section is located substantially near to the first section of the bed, besides, a part of the second section receives a certain amount of heat from the specified movable first hydrocarbons, but is not heated conductively with heat from the first heaters. Then heat is supplied into the second section with the help of one or more heaters arranged in the second section, for additional heating of the second section. Pressure is varied in the heated sections of the bed to change and/or control composition of produced hydrocarbons and to manage content of a condensed hydrocarbon relative to a non-condensed hydrocarbon and/or to control density of the produced hydrocarbon.

EFFECT: increased efficiency of method.
