Abstract: The reservoirs in T Oilfield are characterized by anisotropy and inhomogeneity, whose lithology are composed of marine dolomite and limestone. The petro-physical evaluation for the reservoirs was made using data from new logging methods. Based on the conventional evaluation results, the reservoirs were divided into four types, and the accumulation property of the reservoir was evaluated applying XRMI log. WSTT and XRMI were combined to evaluate the validity and distribution of fractures. The log data from NMR was integrated with the conventional log to identify fluids of reservoir and calculate reservoir saturation, which is proved to be correct by using DST results in 25 thin layers of four wells.
