| 摘 要： | 成都洛带沙溪庙组气藏普遍含水，气藏不同位置地层水含量对于天然气的产量及产出时间有很大的影响。地层水矿化度较高，属CaCl2型，具混合水的水化学特征。地层水与天然气共同赋存同一储层中，属于同一压力系统，与天然气伴生产出，无边、底水存在，缺乏有效补给。含水层往往分布于有利的沉积微相一分流河道及河口坝中，厚度大、物性好的砂体含水特征更为明显。通过对该气藏水水化学特征及气水关系的研究，初步明确了该地层水的分布特征。

| Abstract: | The gas reservoir of the Upper Shaximiao Formation in Luodai, Chengdu often contains formation water which has an important influence on gas production. The formation water is characterized by high degree of mineralization. The gas reservoir is aquifer which lies in distributary channel facies and distributary mouth bar and is characterized by tremendous thickness and high porosity. Distribution of the formation water is found out. |
