Zizhou Gas Field is a lithologic gas reservoir,of which the gas and water distribution is dominated by structure and the alteration of sand body condition．SO all sorts of factors should be considered comprehensively in log recognition of reservoir fluid．The crossplot of resistivity·porosity，apparent porosity and formation water porosity are applied to identify the gas layers，water layers and dry layers of the second member of Shanxi Formation in Zizhou Gas Field．The resuh shows that these methods can effectively distinguish reservoir fluid．The crossplot of resistivity-porosity and form ation water porosity call be used to distinguish gas layers from water layers，and apparent porosity call be applied to distinguish dry layers from gas layers and water layers clearly．The accuracy of these three methods used together in the study area can reach 95％．
