Numerical modeling of two-dimensional two-phase filtration under frontal drive

Abstract

Abstract The problem associated with the development of gas fields with confined contour water is considered in the paper to increase gas recovery and determine the main indices of the reservoir, as well as the position of the moving boundaries for further development. To conduct a comprehensive study of the process under consideration, a computer model was developed described by a differential equation with the corresponding initial and boundary conditions. An algorithm was developed to solve the problem using the methods of the longitudinal-transverse scheme and the flow version of the sweep method. The results are validated with a test example and an example of a certain real object. The results are shown in the form of tables and isolines. Numerical experiments have shown that using this statement it is possible to apply the developed algorithms and software systems to solve the problem during field development.
