| 摘 要： | 通过20口井的1500个薄片观察,认为四川盆地三叠系雷口坡组发育了石膏溶孔型储层和残留原生粒间孔型储层。两套储层有效孔隙包括残留原生粒间孔、石膏溶孔,发育定位于准同生期。干旱—潮湿气候频繁间互控制了有效储层的发育。储层的时空展布在层位和相带上是有选择性的,为储层预测提供了依据。

| Abstract: | Based on 1500 thin sections from 20 wells,It was found that two kinds of dolostone reservoirs of Triassic Leikoupo Fm.in Sichuan basin.Having undergone complicated diagenesis,the pore space in the reservoirs developed into residual primary intergranular and gypsum-dissolved pores at the early diagenetic stage.The substitution of arid and humid climate frequently controlled the reservoirs developed,which resulted in facies-selective distribution of reservoirs. |
