To the Theory of Filtration of High-viscosity Oil under Thermal Effects

Abstract

A theoretical model of the reservoir development process with high-viscosity oil using the technology of paired horizontal wells is presented. Assuming that the system of two wells is replaced by one given well, through which the reservoir is heated simultaneously and the oil is extracted, numerical solutions have been obtained. The costs of heat for reservoir warming, the evolution of flow rate and the mass of pumped oil for the period under consideration are analyzed at different values of heating temperature, pressure drop and well induction period. The solutions obtained allow us to analyze the most favorable modes of exposure by thermal methods in terms of energy costs.
