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.

摘要： 针对中东T油田碳酸盐岩储层较强的非均质性和各向异性,利用由多种测井新方法得到的测井资料对储层进行了准确、有效的评价。用成像测井资料划分出4种储层类型,并对其进行了储集性能评价;用成像测井资料和正交偶极子声波测井资料评价了裂缝有效性和渗透性;用核磁共振测井资料结合常规测井资料进行了流体识别及饱和度计算。用DST试油资料对4口井25个小层进行了检验,其结果一致。
