摘　　要：根据四川盆地西北部地区下三叠统飞仙关组野外剖面及钻井岩芯的宏观及微观特征,结合常规物性资料,对其储层的主要岩类、储集空间类型、物性、空间展布等特征以及主要控制因素进行了较为深入的研究。其飞仙关组储层主要集中分布于江油鱼洞梁剖面—龙岗68井一带的飞一二下亚段,剑阁地区的飞一二上亚段以及九龙山地区的飞三段;主要的储集岩类为亮晶鲕粒灰岩,其次是(残余)鲕粒白云岩;储集空间以粒间溶孔、粒内溶孔和铸模孔常见,裂缝为主要的渗透空间。储层的形成与演化主要受到沉积相和成岩作用的影响,其中台地边缘鲕粒滩是最有利储层发育的相带,白云岩化作用和埋藏溶解作用导致主要储集空间的形成。According to macroscopic and microcosmic characteristics of the field profiles and drilling cores of the lower Triassic Feixianguan formation in the northwest part of Siehuan Basin, combined with the conventional physical property information, we have a research of char- acteristics, such as petrographic category, reservoir space, physical property and spatial distribution, and the main controlling factors of the reservoir. It＇s shown that the Feixiartguml formation mainly distributes in the lower section of Feixianguanl - 2 in Yutongliang profile- Longgang well No.68 area, the upper section of Feixianguanl - 2 in Jiange area, and Feixianguan3 in Jiulongshan area. The formation and evolution of the reservoir is mainly affected by the sedimentary facies and diagenesis. The most favorable facies belt for reservoir develop- ment is platform edge olitic beach and the dolomitisation and burial dissolution result in the formation of reservoir space.
