ABSTRACT
The process of forcing oil out with immiscible water in the round stratum of final radius at various viscosities and densities of liquids in case of plane radial flow is considered. Iterative difference scheme with combination of straightening of fronts with the method of finite differences is composed for the numerical solution. Alteration methods passage, consisting of the combination of methods of ordinary and matrix passage, is proposed. Results of numerical experiment evidence that the relation of liquids viscosity renders the main influence on the character of force-out process, and allowance for gravity qualitatively changes the picture of the physical process.
