摘　要：溱潼凹陷断阶带断裂系统发育,控制油气聚集的断层主要有F1、Ⅲ、F2、F3及其相应的分支断层,将断阶带分为北部的革舍扭动断裂带与南部的祝庄扭动断裂带.在断层封闭性定量评价与封闭史研究的基础上,结合研究区生排烃史、油源分布特征、油气成藏期以及含氮化合物示踪分析研究表明,断阶带Ⅲ、F2、F3断层在不同的研究区封闭性存在明显的差异,祝庄断阶带Ⅲ号断层垂向封闭性较好,不能成为油气运移的通道,使得角墩子地区的原油主要来源于阜四段源岩,没有阜二段与泰州组源岩的贡献;而F3断层活动期短,侧向封闭性差,也不为油气的运移通道;相比之下,F2断层活动期长,断层垂向封闭性差,而侧向封闭性好,为祝庄地区主要的运移通道,与油气成藏期具有较好的匹配关系,流体包裹体分布与含氮化合物示踪分析也证明了这一点.研究还表明草舍断阶带F2断层活动期短,垂向封闭性好,侧向封闭性弱,不是油气运移的通道;相比之下,F3断层活动期长,垂向封闭性较弱,可以作为油气运移的主要通道,后期主要通过砂体和不整合面运移聚集成藏,与生排烃史、油气成藏期和含氮化合物示踪也具有较好的匹配关系.
