临盘油区复杂断块油藏有效的开发治理技术

Effective Development Technology in Linpan Complex Fault-Block Resverior

针对临盘油区地质条件的复杂性和开发调整的困难度,本文阐述了复杂断块油藏开发治理技术的应用,如精细地质研究技术、剩余油研究技术以及改善水驱油效果的注采调整技术等。精细地质研究技术深化了对油藏的认识程度;剩余油研究技术深化认识不同类型油藏剩余油分布规律,明确了注采调整方向;针对不同类型油藏具有的不同潜力,创新注采调整思路,不断优化注采井网,改善了油藏的开发效果。

Aimed at the complexity of geology and the difficulty of development in linpan oil field, this paper systemati- cally explains the technologies applied in the development of complex fault-block reservoir in recent years, which include fine geology description, remaining oil distribution research and injection-production adjustment for improving water flooding. Fine geology description is applicable to determine the structure of formation. The research of remaining oil distribution is applicable to realize the remaining oil distribution rule. For the potential of various reservoirs, the methods of injection-production adjustment have been developed and the well patterns have been optimized. Development effect of reservoir has been raised and oil recovery of reservoir has been improved.
