Fluid Property Identification Methods for Carbonate Gas Reservoirs in Tazhong Area

Because carbonate reservoir was featured by varied types of reservoir space,strong heterogeneity and great difficulty in reservoir fluid identification,conventional logging data and traditional method were difficult to ensure the accuracy of fluid property identification.By taking the carbonate gas reservoir in Tazhong Oilfield for example,the fluid property identification was studied by conventional logging data,gas logging data and electric imaging logging data.The applicability of all kinds of fluid identification methods for carbonate gas reservoirs is analyzed to verify the validity and applicability of these methods.On the basis stated above,a set of method systems of fluid property identification for carbonate gas reservoirs are established.
