摘　　要：近年来在灯影组地层中的重大突破,为四川盆地在老地层中天然气的勘探展示了良好前景。它们具有层系多、分布广泛、构造单元复杂的特点,在同一油气系统的不同气藏之间常具有一定分布范围和内在联系,在区域上构成一个独立的油气区。影响和控制盆地内形成一个油气区的主要因素是岩相和构造演化条件。文中重点考虑了古今构造、沉积相、储层特征和气井的开发效应等因素,综合分析了川西南部资阳地区气藏成藏条件。In recent years the discoveries of the gas reservoirs are an important breakthrough in Denying Formation, which displays a good natural gas exploring prospect in old carbonate strata of Sichuan Basin. The gas reservoirs have the characteristics of various layers, extensive distribution and complicate structural units. There are certain distributed ranges and internal relations between different gas reservoirs of the same oil and gas system, which constitute independent oil and gas regions. However, the main factors to influence and control the gas reservoir are the lithofacies and structure evolutions. Based on the characteristics of the structure, sedimentary facies, characteristics of the reservoirs and the exploitation effect of gas well, the paper analyzes the hydrocarbon accumulation conditions in Ziyang area.
