Investigation of the two-dimensional problem of filtration of high-viscosity oil in a formation under thermal action

Abstract

A theoretical and numerical study of developing a reservoir with high-viscosity oil using the technology of pair horizontal wells is presented. In a two-dimensional formulation, numerical solutions to the problem of the possibility of extracting high-viscosity oil from a formation with the use of thermal action were obtained. The proposed method is aimed at increasing the efficiency of developing an oil reservoir with high viscosity oil by ensuring a uniform warming up of the developing zone of the field. The adopted model allows to trace a detailed two-dimensional picture of oil filtration in the reservoir and to investigate the main regularities of this process.
