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.
