Numerical simulation of the oil reservoir with regulated disturbances. Oil recovery stability simulation

Abstract

Abstract The article discusses a direction for improvement of the oil recovery stability simulation method. It is shown that the problem of stable productive layer development is solved by setting appropriate goals. To solve the first task, it is necessary to substantiate RFC plugging in the hard mode. The main calculated ratio is the modified Dupuis-Forchheimer and Bernoulli equations based on linear hydraulic resistances of the RFC. To solve the second task, it is necessary to substantiate the choice of resonant frequencies of the oil recovery process in the elastic water-pressure mode. The dependences allow us to distinguish the upper and lower limiting frequencies of the stable oil displacement mode. The solutions make it possible to isolate main conclusions in a complex form.
