| 摘 要： | 鲕粒滩相碳酸盐岩作为储层的气藏是川西北地区下三叠统飞仙关组地层中最主要的气藏类型.影响飞仙关组滩相储层形成的条件较多,主要受构造作用、沉积作用和成岩作用的影响.分析认为同生断裂导致的地貌升降运动对滩体的展布有着明显的控制作用,上升盘边缘易于滩体的形成与演化;高能沉积相带的台地边缘鲕粒滩最有利于储层的形成与演化;经过白云...

| Abstract: | The oolitic beach carbonatite is the most important type of gas reservoir in the Lower Triassic Feixianguan formation in Northwestern Sichuan Province.The forming conditions of the beach facies reservoir of Feixianguan formation consist of mainly structure,sedimentation and lithogenesis.Analysis shows that the elevating movement caused by the contemporaneous faults controls the distribution of beach bodies.The beach bodies are easy to form and evolve on heaved side.The tableland of high energy sedimentary facies is favorable for the forming and evolving of reservoir.The oolitic beach that was reformed by intensive lithogenesis with dolomitization and dissolution would form fine reservoir. |
