Compaction factors of tight reservoirs in the seventh member of Yanchang Formation in the central Ordos Basin during the Late Triassic

  • 摘要: 鄂尔多斯盆地晚三叠世湖盆中部长7油层组砂岩孔隙度平均为9%,渗透率为0.1×10-3 μm2,属致密储层范畴。储集体主要为半深湖—深湖相重力流环境下砂质碎屑流砂岩及浊积砂岩,具有粒度细、填隙物含量高、孔喉形态弯曲复杂,分布集中以及次生长石溶孔发育、原生粒间孔较少等特征。运用铸体薄片、X-衍射、包裹体及电子探针等微观测试分析资料,对储层物性影响因素进行分析。分析认为,沉积、成岩及烃类充注是影响储层物性的三大因素,三者相互作用,相互影响。半深湖—深湖相砂岩特有的沉积特征导致储层压实作用强烈,使孔隙减少22%,是储层物性变差的关键因素;长7烃源岩生、排烃过程中生成的有机酸溶蚀长石等易溶物质,产生次生溶孔,对致密储层物性改造有益;烃类大量生成后的偏碱性环境利于晚期含铁碳酸盐等胶结作用进行,是生排烃高峰期后储层变致密的决定性因素。
