【摘要】 针对高30断块油藏开发中存在的问题,通过油藏数值模拟,研究了该油藏剩余油分布规律,结合储层沉积微相的研究和油藏开发动态分析,认为高30断块剩余油的成因主要是地质(储层非均质性、储层沉积微相、构造等)和工程(井网、注采系统完善程度以及注采强度的大小)两个方面。在此基础上,提出了对高30断块油藏进行开发调整挖潜的方向;经矿场试验后,见到了明显的增油降水效果。更多还原

【Abstract】 In view of the problems in the reservoir production of Fault Block Gao 30, the remaining oil distributional laws in the reservoir are studied through numerical simulation. In combination of studying the reservoir micro-fades with performance analysis of reservoir production, it is considered that the geneses in Block Gao 30 include geologic aspects such as reservoir heterogeneity, reservoir sedimentary micro-fades and its structure as well as include engineering aspects such as well patterns, the integration degree of injection-production system and size of injection-production strength. On the basis mentioned, procedures for tapping the potential of production adjustment are proposed for the reservoir in Block Gao 30, for which obvious results of oil increase and water reduction are achieved in field application.更多还原
