摘　　要：通过对须家河组构造演化、成藏过程、圈闭与烃源岩的时空配置关系等成藏地质条件的综合分析认为,控制川中-川南过渡带须家河组天然气成藏的主要因素包括:充足的烃源岩是油气成藏的物质基础;中三叠统侵蚀面是油气横向运移的主要通道;印支末期古构造带的发育是油气富集的关键,其中后2个因素通过沟通油气源、有利沉积相带和形成圈闭等作用控制着油气的成藏。Based on the integrated research of time-space arrangement affecting the structural evolution,geologic setting of hydrocarbon accumulation,accumulation process,traps and source rocks,it was found that the main controlling factors of gas accumulation included that sufficient source rocks were the foundation of gas accumulation;middle Triassic erosion surface was the primary lateral migration pathway;the palaeo-structural zone was the key of oil and gas enrichment.The above three key elements control the process of gas accumulation through communicating source rocks,favorable sedimentary facies and existing traps.
