川西三叠系飞仙关组海相鲕滩储层为一套亮晶鲕粒灰岩、生物碎屑灰岩和亮晶鲕粒白云岩储层，经过后期多次成岩和构造破裂作用改造而成，溶蚀孔、洞和裂缝十分发育。利用野外地质实测资料和室内分析化验资料，分析了碳酸盐岩储层的岩性特征、储集空间、储层类型及储集性能。储层的储集空间类型多样，孔、洞、缝十分发育，孔隙结构复杂。储层可划分为4 种类型，其中飞三段鲕滩储层质量最优。储层质量的好坏和分布主要受沉积相类型、成岩溶蚀作用强度和构造破裂作用强度的共同控制。运用多因素分析法对该区优质储层的分布区域进行定量评价和预测，结果表明，优质储层主要沿绵阳安县茶坪、楠木园、梓桐宫、绵竹汉旺分布。

The marine carbonate reservoir of Triassic Feixianguan Formation in western Sichuan is mainly composed of sparry oolitic limestone, bioclastic limestone and sparry oolitic dolomite. It was formed by the later multi-stage diagenesis and tectonism, with dissolved pores, caves and fractures developed well. The lithologies, reservoir space,types and accumulation capability of the carbonate reservoir are analyzed by means of geologic survey and laboratory analysis. There are various types of reservoir space, and the pore structure is complex. The reservoir can be divided intofour types, and the oolite reservoir of the third member of Feixianguan Formation has the best quality. The reservoir quality and distribution are mainly controlled by sedimentary facies, denudation and tectonism. The quantitative evaluation and prediction for the distribution of the high-quality reservoir are carried out by using multi-factor analysis method. The result shows that the favorable zones distribute in the oolitie reservoir of the third member of Feixianguan Formation along anxiian Chaping, Nanmuyuan, Zhitonggong and Hanwang in western Sichuan.
