侏罗系油藏开发规律研究及效果评价

Research and effect evaluation of Jurassic reservoir development law

胡尖山油田H151区延9油藏经过近十年开发,已进入中高含水期,后期稳定生产难度逐年加大,因此提高油田开发效果尤为重要。本文通过研究该区延9油藏开发历程、开发特征及规律,借助三维地质建模分析总结剩余油分布规律,确定含水上升受控因素和注采开发单元;结合储层认识和剩余油分布特点,评价更新井和长停井复产效果,为后期油田稳定生产及同类油藏开发提供保证和参考。

H151 Yan 9 reservoir in Hu Jianshan oilfield has been developed for nearly ten years. It has entered a high water cut stage, and it is difficult to produce stable production.So it is very important to improve the development effect. In this paper through the study on the extension of 9 reservoir development process, development characteristics and rules, with3 D geological modeling analysis and summary of the distribution of remaining oil, determine the rise of water controlled factors and injection production development unit,combined with the understanding of reservoir and residual oil distribution characteristics and evaluation of new wells and a long stop wells resume production effect, has certain guiding significance for the oilfield stable production and similar reservoir development in the later stage.
