Engineering Physics Annotation << Back TEMPERATURE EFFECT IN NONSTATIONARY FILTRATION O.V. AKHMETOVA, M.A. ZELENOVA, N.A. UNSHCHIKOV The results of a computational experiment based on an asymptotic model of nonstationary heat transfer when filtering hydrocarbons in a layered inhomogeneous medium in an unsteady pressure field are described. The construction of the calculation formula is based on the theory of the barothermal effect and required the solution of two problems (temperature and hydrodynamic), which contain conjugation conditions at the conditional interface between the layers. The solution of interrelated problems of temperature and pressure fields in a porous reservoir in the selection of hydrocarbons from it was found using the asymptotic method of a formal parameter. A computational experiment shows that the temperature effect caused by filtration in a non-stationary pressure field is mainly influenced by flow rate, oil-saturated average area, thermal and physical characteristics of the filtering fluid and surrounding rocks, as well as the horizontal component of the permeability of the middle layer. It practically does not depend on the hydrodynamic characteristics of the environment. Key words: pressure gradient, formation temperature signal, heat source.
