茨榆坨油田C9区块油藏地质体精细研究

摘要

茨榆坨油田C9区块已进入开发后期,地质条件复杂,开发时间长,水淹程度较高,剩余油分布复杂,稳产难度越来越大.本次研究通过应用地质体等时解析技术对C9区块油藏地质体进行精细研究,解决了开发以来存在的主力含油层位不确定、油水关系矛盾、油藏类型认识不清等问题,明解了该区块成藏条件匹配性及油气成藏特征,为老区挖潜提供了可靠依据和有利方向.%The C9 Block of Ciyutuo Oilfield has been developed for many years. As a result, the distribution of remaining oil is complicated, which makes stable yield more and more difficult. The author studied the reservoir geological body by geological isochronic analysis techniques, and solved main existing problems. At the same time, it clarified the matching condition of reservoir-forming and accumulation characteristics. Therefore, it provided a reliable basis for the development of developed reservoirs.
