摘要
为提高J11断块高采出程度、特高含水“双高”砂岩油藏采收率,通过对该油藏开发情况的定位和油藏地质模型的精雕细刻,构建剩余油分布类型,分级描述水淹程度,分析控制剩余油分布的地质因素及水淹规律,提出剩余油的分布类型,从而确定J11油藏二次开发的“二三结合”技术策略,给出了不同类型剩余油的挖潜方法和开发方式,打通进入双高油藏开发后期的新出路。
In order to improve the recovery rate of sandstone reservoirs with high depletion and high water cut in the J11 fault block,a comprehensive approach was adopted.Firstly,the development status of the reservoir was assessed,and a refined geological model of the reservoir was established.Then,the distribution types of remaining oil were identified,and the degree of water flooding was evaluated.Subsequently,the geological factors controlling the distribution of remaining oil and the patterns governing water flooding were analyzed.Based on these analyses,the distribution types of remaining oil were determined.Finally,a“Combination of Two and Three”technical strategy was proposed for the secondary development of the J11 reservoirs.This strategy provides tailored methods and development models for tapping different types of remaining oil,opening up new pathways for the late-stage development of reservoirs with high depletion and high water cut.
