本文主要研究内容
作者陈聪,张健,罗冰,文龙,林怡,张亚,谢忱,徐国盛（2019）在《四川盆地西北部地区中三叠统——古生界压力封存箱与油气成藏》一文中研究指出：四川盆地西北部地区(以下简称川西北)龙门山断裂带北段存在着常压、高压和超高压等多个压力带,前人在研究该区"压力封存箱"时,通常以目前该盆地超压区的分布为依据划分出"压力封存箱"的范围,但是对于压力封存箱的演化及其与油气成藏关系的研究则鲜见。为此,利用井震联合解释、Easy%R_o热动力学模型、平衡剖面技术等手段,刻画川西北中三叠统—古生界压力封存箱的构成,恢复其形成过程,并研究封存箱内中二叠统栖霞组和中泥盆统观雾山组气藏的形成演化过程。研究结果表明:①川西北中三叠统—古生界存在自源型异常高压封存箱,封存箱范围西至①号隐伏断裂,东至九龙山构造,北至米仓山古隆起南缘山前断褶带构造,南至双鱼石构造南段,该压力封存箱以九龙山构造至双鱼石构造带中线为界分为东、西2个次箱;②该压力封存箱距离龙门山断裂带越远超压程度越高,压力封存箱与外界存在着明显的压力差,箱内压力系数介于1.4～2.0,箱外为正常压力系数;③古生界压力封存箱形成于印支运动早期,经燕山运动和喜马拉雅运动调整形成现今格局;④中三叠统—寒武系油气为喜马拉雅期所形成的箱内成藏,压力封存箱内存在着多套烃源灶,气源充足,顶板和隔板具有较强的封盖性,源储匹配良好,油气优先富集于距离箱顶板较近的优质储层中。结论认为,该区古生界深层海相地层具有较大的油气勘探潜力,其中双鱼石—中坝地区栖霞组为最有利的勘探层系,观雾山组是潜在的有利勘探层系。
