| 摘 要： | 油气输导体系研究是油气成藏机理研究的重要内容之一.采取宏观与微观相结合的研究思路,综合应用录井、测井、地震、分析测试等资料,识别苏北盆地海安凹陷泰州组油气运移范围和路径,指出了油气运移的优势通道,分析了海安凹陷泰州组输导体系的特征及其组合方式.泰州组一段3套骨架砂体和系列断层相互配置,形成了连通砂体型、断层型、砂体—断层复合型3种输导体系类型.输导体系类型决定了该区的油气成藏模式,在泰州组一段1砂组,以连通性较差砂体为输导体系,发育岩性油气藏和构造-岩性油气藏；在2+3砂组中,以断层或砂体—断层为输导体系,发育构造油气藏.综合研究表明,海安凹陷泰州组的砂体和断层是油气运移优势通道,以连通砂体为主要运移通道的油气藏常形成于距烃源层较近或相邻的层位；而以断层为垂向运移通道的油气藏常在断层带附近多层叠置. |

| Abstract: | Petroleum-conduct system is an important part of the reservoir mechanism research.Based on the data of drilling core, well-logging,seismic and analytical testing in Hai'an sag,pathway and scope of hydrocarbon migration is identified in Cretaceous Taizhou formation through macro-and micro-method.Sandbodies and faults are main migration paths,which construct petroleum-conduct system in Taizhou formation of Haian sag.Types of petroleum-conduct system,including sandbody,fault and sandbody-fault composite,contro... |
| Keywords: | hydrocarbon migration conduct system perferential pathway hydrocarbon accumulation Taizhou formation Hai'an sag |
