Abstract: The reservoir evaluation technology multiple well-loggings in oil pool description can provide a great number of reservoir parameters,By predicting on the inter-well loggingparameters of reservoir,the three-dimensional data base of reservoir could be established.Such a data base can effectively reveal the anisotropism of reservoir and the distributivepattern of petroleum,and it reaches very high precision which has been proven by oil pro-ductional tests.Using this data base and the isogram of reservoir parameters to do the es-timation of hydrocarbon reserve would be more precise than using traditional method;fur-thermore,artificial errors can also be avoided as much as possible.
