延长川口油田丛131井区主要注采矛盾为部分井水窜、水淹,多数井注水效果不明显。本文从细分层做起,进行测井相微相边界确定,储层基本特征及地应力情况分析、天然裂缝分布规律研究、注采动态分析及单井矛盾定位,措施的适应性分析,最后,结合具体井的重点解剖,提出了十大解决对策及分步实施建议。
Extending the main injection and production contradictions in Cong 131 of Kawaguchi oilfield is that some of the wells are water channeling and flooding, and the effect of water injection in most wells is not obvious. This paper starts from the subdivision level, and conducts the determination of logging facies and microfacies boundaries, the analysis of reservoir basic characteristics and stress, the study of natural fracture distribution, the dynamic analysis of injection and production, the contradiction between wells and the adaptability of measures, and finally , Combined with the focus of specific well anatomy, put forward the top ten solutions and step-by-step implementation of the recommendations.
