| 摘 要： | 在复杂断裂带,断层封闭性研究极其重要。综合分析溱潼凹陷草舍构造断层两盘的岩性配置关系、泥岩涂抹系数、断面承受应力、断裂活动期与生排烃期的配置关系,认为草舍构造断层侧向封闭性整体较差,可以作为油气侧向运移的通道。F3断层活动期与生排烃期匹配,阜二段以上层段断面压力不大,在三垛组沉积末期该断层垂向开启,是阜二段油气纵向运移重要通道。

| Abstract: | In complex fault zones, it is important to study fault sealing performance. By comprehensive analysis of the lithology con-figuration relations of two fault walls, shale smear factors, fault bearing stress and the relation between fault moving periods and hy-drocarbon generation and expulsion periods of Caoshe area in Qingtong sag, it is considered that the overall lateral fault sealing per-formance of Caoshe structure is poor to make it the lateral migration channel of the oil and gas. That the fault moving periods of F3 matched with the hydrocarbon generation and expulsion periods, fault section pressure above Ef2 formation is low, and this fault is open in vertical direction at the end of the sedimentary of Sanduo formation make it to be the important pathway for the oil and gas migration of Ef2. |
