| 摘 要： | 隔层是潜山内幕油气分布的重要控制因素之一。从冀中坳陷潜山内幕的勘探实践出发，综合利用地质、地震、测井、分析化验等资料，对潜山内幕隔层的岩性特征、电性特征、地震反射特征及其分布特征等进行了分析。研究结果表明，冀中坳陷潜山内幕隔层岩石类型多样，且具有较好的封堵性能，其在纵向及横向上的分布特征影响着潜山内幕油气的分布。根据潜山内幕隔层与油气的配置关系，将隔层控制下的潜山内幕油气分布模式划分为顶部遮挡型、底部遮挡型、侧向遮挡型和顶底夹持型等4种类型。中央隆起带潜山深层内幕圈闭、斜坡带和断阶带内幕圈闭是冀中坳陷今后潜山内幕油气藏勘探的有利方向和区带。

| Abstract: | The interlayers of inner buried hills are the main factors that control the hydrocarbon distribution. Starting from the exploration practice in Jizhong depression, this paper studies the characteristics of lithology, resistivity, seismic reflection and distribution of interlayers using the seismology, geology, logging and assay data. The result shows that the interlayers of inner buried hills in Jizhong depression have multiple types of rocks with preferable sealing ability. The distribution characteristics of interlayers in horizontal and vertical directions influence the hydrocarbon distribution of the inner buried hill reservoir. According to the relationship of interlayer and hydrocarbon, the patterns of hydrocarbon distribution can be classified into four main types,ie. top barriering,bottom barriering,lateral barriering and top-bottom sandwich. Explorations should be focused on the deep inner traps in the central uplift belt, and the inner traps of the slope belt and the fault step belt. |
