摘　　要：河南油田主力开发区已进入高含水开发后期,后备资源接替严重不足成为制约油田发展的瓶颈。“九五”期间,河南油田加大了难采储量评价和动用的工作力度,按照“整体研究、系统解剖、优选目标、重点突破、滚动发展”的工作思路,对目标区进行综合地质研究,同时运用简易开发、大斜度定向井、稠油冷采等多种开采方式动用难采储量,使资源利用程度逐年提高。“九五”期间共系统开发难采储量437×104t,增加可采储量63.3×104t,建成原油生产能力6.6×104t。文中以张店、新庄油田为重点,探讨了提高难采储量动用程度的途径。The major blocks in Henan oilfield have entered late development stage with high water-cut and severely in-sufficient back-up resources are the bottlenecks that re-strict oilfield development.Large efforts were put on e-valuation and production of difficult-to-recovery reserves during the″Ninth Five Year Plan″.Through comprehen-sive geologic study,deployment of highly deviated direc-tional wells and cold production of heavy oil,4.37mil-lion tons difficult-to -recover reserves were brought into production and633,000tons of recoverable reserves were added.Measures to bring more difficult-to-recover re-serves into production are presented taking Zhuangdian and Xinzhuang oilfields as examples in this paper.
