Description:
For the A South and Γ North reservoir of Zhanzhol oil field in Kazakhstan, only the oil rim was developed since 1983. Recently, the gas cap of A South reservoir was exploited in September, 2014. However, the concurrent production of gas cap and oil rim is likely to cause the pressure imbalance, which will lead to the worse development effect of the whole reservoir. In order to acquire the efficient concurrent production of gas cap and oil rim, the technique policy charts of concurrent production are established, involving three types of development mode such as depletion development, barrier water injection development and barrier plus pattern water injection development. For depletion development, rational oil recovery rate increases with rational gas recovery rate; for barrier water injection development, the rational position of barrier water injection well moves towards the inner oil-gas contact with the increase of gas recovery rate and injection-production ratio; for barri...
