Numerical model of oil, water and gas flow in oil pools

Abstract

During the oil well usage its flow rate inevitably lessens. As a result the oil production enterprises must solve the most important problem of the oil extraction intensification. When solving filtration problems (there is a great set of problems; here we will deal with one of them including physical processes, difficulties and problem setting-up) ordinarily use well-known problems. However, in many cases, for example, when describing thermogas-chemica modification (TGCM) there capacity is insufficient. For example, one needs describing of more than two phases, taking into account chemical reactions and so on. We produced a program which clears this trouble. This program can model main features of the TGCM case: many-phase and non-isothermal process, non-one-dimensional flow. As a result we can better tune calculation programs for specific deposits by taking into consideration of geologic peculiarities and near-well zone defects occurred as a result of previous usage.
