在二叠的 Changxing 和三叠纪的 Feixianguan 形成的礁石和鲕状的煤气的水库在四川盆，而是累积规模的 Luojiazhai-Puguang 和 Longgang 区域被发现了，丰富和分发模式极大地不同。事实上，二个区域比他们有类似的有更多的差别。类似包括：(1 ) 礁石和鲕状的水库的孔的岩性学，性质和类型在二个区域主要是一致的；(2 ) 开发得好的地区性的 caprocks 封上液体系统；并且(3 ) 累积过程历史与在一个早阶段收费的液体烃，在一个迟了的阶段在高度裂开进气体到在成熟上的舞台，在一个高举的阶段的煤气的水库的调整，和最后的水库产生。差别包括：(1 ) 在被油类型统治的 Luojiazhai-Puguang 区域的煤气的累积击碎气体，与多重、足够的煤气的来源一起，与在被与不够的煤气的来源一起的采购煤的气体统治的 Longgang 区域的煤气的累积形成对照；(2 ) 异质和在比在 Luojiazhai-Puguang 区域强壮的 Longgang 区域的水库的水平差异；并且(3 ) 在 Luojiazhai-Puguang 区域的深、大的差错的开发那连接来源，水库和移植小径，在 Longgang 区域与糟糕发达的差错形成对照，在旁边地可变的破裂是主要移植小径的地方。因为这些差别，丰富的大规模控制在结构上的煤气的累积在 Luojiazhai-Puguang 区域被开发，而岩性学在累积是小规模的并且有更低的煤气忍受的丰富的 Longgang 区域在煤气的累积起一个更重要的作用。我们建议为礁石和鲕状的煤气的累积的那未来探索应该在 NE 四川和 NW 四川 Jiulongshan 被加强。特别地，在 Longgang 之间的过渡地区和 Kaijiang-Liangping 海湾为新发现有最好的潜力。

英文摘要：

Reef and oolitic gas reservoirs in the Permian Changxing and Triassic Feixianguan formations have been discovered in both the Luojiazhai-Puguang and Longgang areas of the Sichuan Basin, but the accumulation scale, abundance and distribution patterns differ greatly. In fact, the two areas have more differences than they have similarities. Similarities include： （1） the lithology, properties and types of porosity of the reef and oolitic reservoirs are primarily consistent in the two areas; （2） well-developed regional caprocks that seal the fluid system; and （3） accumulation process histories, with liquid hydrocarbon charging at an early stage, cracking into gas at a high to over-mature stage, adjustment of gas reservoirs at an uplifting stage, and final reservoir generation at a late stage. Differences include： （1） gas accumulations in the Luojiazhai-Puguang area that are dominated by oil-type cracked gas, with multiple and sufficient gas sources, contrasting with gas accumulations in the Longgang area that are dominated by coal-sourced gas with insufficient gas sources; （2） heterogeneity and horizontal diversity of reservoirs in the Longgang area that are stronger than in the Luojiazhai-Puguang area; and （3） the development of deep and large faults in the Luojiazhai-Puguang area that link source, reservoir and migration pathways, contrasting with poorly developed faults in Longgang area, where laterally variable fractures are the major migration pathway. Because of these differences, abundant large-scale structurally-controlled gas accumulations are developed in the Luojiazhai-Puguang area, whereas lithology plays a more important role in gas accumulation in the Longgang area where accumulations are smaller-scale and have lower gas-bearing abundance. We suggest that future exploration for reef and oolitic gas accumulations should be strengthened in NE Sichuan and NW Sichuan Jiulongshan. In particular, the transitional zone between Longgang and Kaijiang-Liangping Bay has the best potentia
