STUDY OF REGULARITIES OF DISTRIBUTION OF WATER BODY IN MA 5 RESERVOIR OF MAJIAGOU FORMATION OF LOWER ORDOVICIAN IN SHAN 155 WELL FIELD OF JINGBIAN GAS FIELD IN ORDOS BASIN
鄂尔多斯盆地靖边气田陕155井区下奥陶统马家沟组马五储层水体分布规律研究

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.
