摘要

Algorithms have been developed, making it possible to carry out a rapid analysis of the development of a heat front in a producing reservoir. Expressions have been obtained for determining the coefficient of the fluid′s heat exchange with the rocks surrounding the reservoir using an analytical solution of a one-dimensional nonstationary problem of temperature field propagation into the surrounding rocks and a numerical solution of a three-dimensional nonstationary problem of heat transfer in a layered inhomogeneous reservoir. An algorithm is suggested, based on a numerical and numerical-and-analytical solutions of an inverse problem for a more accurate determination of the heat-transfer coefficient. This makes it possible to perform one numerical calculation of a solution to the problem of heat transfer in a complete formulation using a hydrodynamic simulator.
