    摘要： The method of thermal-mine working of an oil reservoir includes providing at least one injection gallery and a recovery gallery and drilling therefrom, respectively, injection and recovery wells. The formation is heated up by feeding a heat carrier into the injection wells, and oil with associated water thus evolved is withdrawn through the recovery wells. The associated water is separated from the oil and pumped into the oil-bearing formation, to assist in driving-out the oil. The recovered oil is conveyed to the ground surface through the mine workings. At least one auxiliary well is also drilled, to connect directly the recovery gallery and the injection gallery; and, a pipe line is mounted in this auxiliary well and spaced from the walls of the bore of the auxiliary well. Oil and associated water are separated directly within the recovery gallery. The associated water thus obtained is conveyed via the pipe line to the injection gallery, to be fed into the injection wells, while at the same time oil and associated water are recovered through the annular space between the pipe line and the walls of the auxiliary well.

    摘要： The method of thermal-mine recovery of oil and fluent bitumens or kerogens includes providing a system of mine workings above an oil-bearing formation and drilling from these workings and from the ground surface a series of injection wells into the oil-bearing formation. An operation gallery is provided within the oil-bearing formation, from which a system of horizontal and inclined recovery wells is drilled. Then a heat carrier is positively injected into the oil-bearing formation to heat it to a temperature whereat the oil attains the required fluidity within the formation. Then a fluid is charged into the formation to force the oil from the oil-bearing formation into the horizontal and inclined recovery wells, toward the operation gallery, from which the oil is directed to the ground surface. The improvement of the method resides in that the heat carrier is injected into the formation through the horizontal and inclined recovery wells extending substantially across the predominant direction of the highly permeable zones of the oil-bearing formation, and, following the heating of the formation to the abovesaid temperature, the injection of the heat carrier is terminated, and the fluid is charged into the injection wells having minimized association with the highly permeable zones of the oil-bearing formation, to force the oil from the oil-bearing formation through the recovery wells toward the recovery gallery.
