摘要
综合运用最新的钻井、测井、地震资料,基于济阳坳陷构造演化叠合关系控制下的潜山发育过程分析,揭示潜山展布规律,区划潜山成因类型,明确潜山结构差异,旨在为潜山油气勘探提供指导.研究结果表明:济阳坳陷中生代NW向反转断层控制的凸凹格局与新生代NEE向张性断裂控制的凸凹格局的垂向叠合,控制了NW向和NEE两组潜山带的发育,形成了济阳坳陷“七纵四横”的潜山分布格局;依据潜山的形成与演化过程,可将济阳坳陷潜山分为3大类7小类;各类型潜山在地层格架、构造样式、隆剥沉埋等方面的差异,导致其油气来源、有效储层、内幕结构等油气成藏条件的不同,其中NW-NEE向叠合山油气成藏条件最佳,应成为今后济阳坳陷潜山油气勘探的重点靶区.
Based on the comprehensive application of the latest drilling, logging and seismic data and the structural evolution superposition relationship in the Jiyang Depression, this paper reveals the distribution law, genetic types and the internal structural differences of buried-hills, so as to provide guidance for hydrocarbon exploration. The results show that the vertical superposition of the basin structures controlled by the Mesozoic NW-trending inversion faults and the Cenozoic NEE-trending extensional faults influences the development of the NW-trending and NEE-trending buried-hill belts, forming the “seven-longitude and four-latitude” distribution pattern of buried-hills in the Jiyang Depression. According to the development and evolution of buried-hills in the Jiyang Depression, they can be classified into three categories and seven sub categories. The differences in stratigraphic framework, structural style and burial history of various types of buried-hills lead to different hydrocarbon accumulation conditions such as oil and gas source, effective reservoirs and internal structures. NW-NEE superimposed hills have the best hydrocarbon conditions and should become key target areas of buried-hill oil reservoir exploration in the Jiyang Depression in the future.
