摘　　要：大牛地气田碳酸盐岩缝洞型储层的非均质性、泥浆的侵入、矿化度的高低、井径扩径等因素,造成对碳酸盐岩流体性质的识别成为世界性难题,对此,根据现有资料统计和分析,采用7种气、水层识别方法,确定了马五5亚段储层、气层、气水同层、水层的识别标准。Daniudi gas field lied in the north of Ordos basin, owing to the factors such as reservoir heterogeneity, mud invasion, high and low degree of mineralization and enlarged borehole diameter, it is extremely difficult to identify fluid properties of carbonate rock in Daniudi gas field. Therefore, in accordance with existing data statistics and analysis, 7 methods have been adopted in gas and water layers identification and then the identification standards of reservoirs, gas layers, water layers and gas and water mixed layers have been established.
