Research on Stable Production Technology for Complex Fault Block in High Water-Cut Period

For matured oilfield which has stepped into high water-cut period, it usually faces much problem, such as serious contradiction between injection and production, increasingly complex oil distribution, declining production, etc. We took Gang-Dong oilfield as an example in this paper to analyze the well conditions, well pattern, development status and well nets reconstruction, and to optimize the development index by reservoir engineering. In this way, the development effect of Gang-Dong oilfield has been improved. The result can be used as a reference for similar oilfield.
