The heterogeneity and anisotropy of the carbonate rock strata in the carbonate basement reservoirs exhibit significant magnitude. The impact of this factor on the vertical resolution and radial detection depth of various logging methods surpasses that caused by variations in reservoir fluid properties. Therefore, it is necessary to analyze the influence factors before determining the fluid properties of reservoirs, involving reservoir type, water salinity, induced porosity, matrix porosity, fracture dip angle, shale content, oil saturation, resistivity and its amplitude difference. And among them, the largest influence factor is the types of storage space, which can cause fluids occurring in variable states, resulting in challenging fluid evaluation. At present, due to limitations of individual methods, which may lead to some wrong results, appropriate interpretation methods are employed to determine the fluid properties under certain conditions. This paper mainly introduces five well logging techniques to recognize the fluid properties of carbonate basement reservoirs. It includes resistivity method (Well logging cross plot of Rd/Rs and Rd is established based by different reservoir types, and this method exhibits significant efficacy in the vuggy reservoirs), normal distribution method (This method is applicable to vuggy reservoirs and certain fracture-vuggy reservoirs in Jizhong depression), oil saturation calculation (It includes two aspects, effect of fractures on resistivity and oil saturation determination by resistivity correction), array acoustic data to recognize gas layer, and electrical imaging data to determine fluid properties.
