Reservoir formation and modification controlled by thermal events in the Xihu Sag, East China Sea Basin

  • 摘要: 东海盆地西湖凹陷近年来的勘探研究表明,与热事件相关的溶蚀作用是深部储层(≥3 300 m)次生孔隙发育的重要因素之一。通过利用磁场、热场及三维地震对研究区火山发育特征的研究,结合薄片观察、场发射能谱环境扫描电镜等实验方法及物性分析等资料,对西湖凹陷深部储层与热事件相关的溶蚀作用进行研究。结果表明,砂岩储层受热事件的改造作用主要表现在热流体携带酸性物质及加速烃源岩热演化释放有机酸等因素导致储层次生孔隙发育。研究了热事件对不同储层发育部位的改造作用,探讨了热液事件改造储层的机理,进而指出了热液改造影响储层的区域分布规律。
