Filippov, O. Korkeshko, P. Chiganov] The problem of the thermal action on oil and gas strata by injection of a heating medium using expansion in a small parameter is reduced to an infinite sequence of boundary‐value problems that are solved by the method of integral transforms. It is shown that, with an appropriate selection of the small parameter, the zeroth‐order approximation corresponds to a space‐averaged (across the stratum thickness) solution of the main problem and leads to a "concentrated‐capacity scheme” that is constructed assuming that the stratum temperature is independent of the vertical coordinate. The first approximation permitted marked refinement of calculations according to the "concentrated‐capacity scheme” and an evaluation of its error. Space‐time temperature distributions are presented that have been calculated using the analytical solutions obtained. Plenum Publishing Corporation, 2000 Filippov A.
