渡口河、罗家寨气田位于四川省宣汉县和重庆市的开县境内。在三叠系飞仙关组中均发现了储量较大的气藏 ,渡口河探明储量 2 71.6 5× 10 8m3 ,罗家寨探明储量 5 38.4 0×10 8m3 ,控制储量 32 6 .72× 10 8m3 。对已获气井产能的分析关系到对气藏高效、合理的开发。各气藏已获气 Dukou River, Luojiazhai gas field is located in Xuanhan County, Sichuan Province and Kaixian in Chongqing. In the Triassic Feixianguan Formation, large reserves of gas reservoirs were found. The proven reserves of the Dukouhe River was 2 71.6 5 × 10 8 m 3, that of Luojiazhai was 5 38.4 0 × 10 8 m 3, and the control reserves were 32 6 .72 × 10 8m3. The analysis of the gas wells that have been acquired has implications for the efficient and rational development of gas reservoirs. Each gas reservoir has been gas
