| 摘 要： | 通过对苏里格西部地区上古生界烃源条件、储盖组合及成藏过程、成藏控制因素分析表明:气水分布受烃源岩厚度、生烃强度、运移动力和通道、异常压力等条件的控制。源储剩余压力差是天然气从烃源岩通过输导通道进入圈闭最主要的动力,砂体-孔隙型、微裂缝等为天然气的运移提供了有利的输导通道,异常压力封闭对整个研究区上古生界的天然气聚集和保存起着重要的作用。

| Abstract: | A study of hydrocarbon source,source-reservoir-caprock association,and process and control factors of migration and accumulation of hydrocarbon indicates that distribution of gas and water is controlled by thickness of source rock,motive power and channel of migration and pressure.Source-reservoir residual pressure difference was major motive power of gas migration.Pore and fissure provided migration channel.Abnormal pressure seal was of importance to accumulation and preserve of hydrocarbon in the Upper Pa... |
