Influence of water-dissolved gas on development parameters of hydrocarbons deposits

UDK: 622.276.346.2
DOI: 10.24887/0028-2448-2018-04-52-54
Key words: gas content, blue gas, phase equilibria, oil, associated petroleum gas
Authors: N.A. Gultyaeva, E.V. Bobrov (Tyumen Branch of SurgutNIPIneft, RF, Tyumen)

The analysis of height of GOR shows that along with intrastratal gas liberation in a bottom hole and in horizontal wells, equipped by centrifugal pump at the decline of coalface pressure below of bubble point the reason of receipt of gas a cut in the obtained water. According to executed estimation, depending on PT-terms at a frequent contact with oil in water it can be dissolved from 1 to 2.5-2.7 3/3 gas, that at water cut to 90-93% appears a substantial size from the point of view of the taken away volumes of gas. Thus, as the prepared begun to swing water is gas-free before beginning to swing, then in the process of circulation in a reservoir, diffusive of components of hydrocarbon (especially methane, nitrogen, carbon dioxide) is marked to the achievement of the state of saturation with the decline of mobility of remaining oil.
