金湖凹陷所有已发现油田基本与断层有关 ,文章通过对断层封闭机理研究 ,对断层活动期及其所控制圈闭的遮挡体的砂泥岩比例等对断层横向封闭性进行了研究 ;同时从凹陷内大量录测井、试油、油藏解剖出发 ,定性分析了断层纵向封闭性特征 ,通过圈闭的油气充注方式及其油气藏的油、水分布关系等来判别断层纵向封闭性。对凹陷内断层横、纵向封闭性研究总结了金湖凹陷断层封闭规律。
All the discovered oil fields in Jinhu depression are basically related to faults. Based on the research on fault sealing mechanism, the horizontal sealing of the fault is studied for the active faults and the ratio of sandstone and mudstone of the shield bodies under the controlled traps. At the same time, Based on a large number of logging wells, test oil and reservoir anatomy, the longitudinal seal characteristics of the fault are qualitatively analyzed. The longitudinal seal of the fault is judged by the trapped oil and gas filling pattern and the oil and water distribution of the reservoir. The horizontal and vertical sealing of the faults in the sag are summarized and the fault sealing rules in Jinhu sag are summarized.
