针对文明寨油田局部构造认识不清、层间动用状况差异大、剩余油分布规律复杂、井况恶化等各种矛盾,介绍了油田高含水、高采出程度开发期保持连续5 a 稳产的途径,阐述了以强化构造认识,加大注水、产液结构调整,加强剩余油分布规律研究为主的各种具体方法和措施,进一步总结了油田开发取得的显著效果,为复杂断块油田高含水开发阶段保持稳产提供了一个借鉴实例。

Aimming at varies contradictions existing in the stage of high water cut and high recovery percent ,for instance , the understand to the local structure of Wenmingzhai Oilfield being unclear , the status of produced interbedded oil being very different , the regulation of distributing of residual oil being complex , well’s condition being worse , this paper introduces the measures to keep the oilfield production steadily in continuous five years in the stage of high water cut and recovery percent , expound a series of measures to strengthen the understand to underground structures ,increase water injection , adjust the structure of producing liquid , strengthen the study of the distributing regulation of residual oil , the remarkable effect in development was summed up , sothe measures provides a reference to keep the production steadily in the stage of high water cut for this kind of oilfield.
