ON THE THEORY OF EXTRACTION OF HIGH-VISCOSITY OIL FROM THE STRATUM UNDER THERMAL ACTION

The authors have presented a theoretical model of the process of development of a stratum with high-viscosity oil by the technology of double horizontal wells. In this model, a system of two wells is replaced by one reduced well through which the heating of the stratum and the extraction of the oil are implemented simultaneously. Numerical and analytical solutions of the problem have been obtained. The expenditure of heat to warm up the stratum, the evolution of the well discharge, and the mass of pumped oil in a certain time interval have been determined. The obtained solutions make it possible to select the mode of thermal action on the stratum that is the most effi cient as far as power consumption is concerned.
