摘　　要：地处四川西南部威远背斜北翼的资阳地区，背斜及断层稀少，圈闭类型复杂。通过对区内灯影组沉积、成岩、构成及储层特征等方面的研究，认为主要有残丘和风化壳型、岩溶溶洞型、透镜型、裂缝型和古残留背斜型等5类有利于天然气聚集的储渗体圈闭，这些储渗体圈闭是各种地质因素共同作用的产物，它们对灯影组气藏的形成起着重要的控制作用。Ziyang area is located at northern flank of Weiyuan anticline, southwest Sichuan, where developed complicated trap types with few faults and anticlines. By study of sedimentation, diagenesis, tectonism and reservoir rocks, it is presented in this paper that there are five kinds of traps which are favourable for gas accumulation, i. e. residual hills, weathering crust, karst vugs and caves, lens, fissures and old relic anticlines. The traps resulted from vary geological agents play an important role in controlling the formation of the Dengying gas accumulation.
