通过对新老资料的消化吸收并结合地质、测井、测试及开发动态情况，着重分析了控制地层水聚集的地质因素和地层水的聚集规律，划定出了水体分布范围，并把水体分布分为3种类型，即相对富水区、潜在含水区和无水区，进而指出区域构造特征、现今埋藏条件下的小幅度构造、储层的非均质性和构造反转前后的气排水形式等是影响气水分布的主要因素。

At the base of summarizing the former product, absorbing the old and new information and synthetizing the data of geology, well logging, testing and exploiting dynamic state, the emphasis of study is put on the control geologic factors and regularities of distribution of water body, then the demarcation of range of water body. By the study, the main factors affecting the distribution of gas and water are the tectonic characteristic of the region, the small structure in the nowadays condition, the heterogeneity of the reservoir, and the repulsion of gas to water in the period of tectonic reversal. Distribution of water body of the region is divided into 3 kinds areas of relative rich water, potential containing water, and without water.
