| 摘 要： | 通过储集层成岩作用与有机包裹体的研究认为,研究区储集层有机包裹体主要通过交代和重结晶作用而形成,有各种相态形式,主要分布在石英颗粒内溶蚀缝或孔隙中,构造裂缝中基本未见有机包裹体。上三叠统储集层包裹体丰度明显高于侏罗系沙溪庙组。香二气藏砂岩有机包裹体均一温度主峰在 10 0～ 110℃;沙溪庙气藏砂岩有机包裹体均一温度主峰在 90～ 10 0℃。香二气藏形成时间早,经历了印支期少量注入到印支期末-喜山早期大量注入,再到喜山晚期调整、部分注入的过程。沙溪庙气藏天然气注入则主要发生于喜山运动期。

| Abstract: | In this paper, the author researched diagenesis and organic inclusion in reservoir. In this area, organic inclusions were mostly formed by recrystalization and metaspmasis and with various phases. They distributed chiefly in dissolved seams and pores in quartz grains and not in structure slot. The organic inclusion abundance in Upper Triassic was more than that in Shaximiao Formation. The homogenization temperature of organic inclusion was between 100℃ and 110℃ in the second interval of Xujiahe Formation and between 90℃ and 100℃ in Shaximiao Formation. The second segment gas reservoir of Xujiahe Formation was formed earlier and underwent the course early from small charge to large charge and late again from adjustment to small charge. The gas reservoir of Shaximiao Formation was formed in the course of Xishan Tectonic Movement. |
