摘　　要：相对于碎屑岩储层,碳酸盐岩储层岩性复杂和储集空间类型多样给适用于岩性单一的均质模型测井评价方法带来了挑战。为进一步提高碳酸盐岩储层参数计算精度,通过对中东M油田具有放射性的白云岩的精细处理、储层参数敏感性分析、最优化处理模型和解释参数等方面进行的准确、有效的评价,建立了以岩性识别为核心的碳酸盐岩储层测井评价技术。应用效果表明,通过储层参数精细化处理与综合解释,其结果可以满足该油田储层评价和储量计算的要求。As compared with clastic reservoir, car- bonate reservoir is more complex in lithology and has various types of reservoir space, giving a cha lenge to the logging evaluation method of sirnp and homogeneous litho ther improve the calcu ogie model. In order to fur- ation accuracy of carbonate reservoir parameters, a logging evaluation tech- nique with lithologic identification as its core was developed, by several aspects of effective evaluation in M oilfield, Middle East, such as the refined pro- cessing of radioactive dolomitite, the sensitivity anal- ysis of reservoir parameters and the optimization of model and interpretive parameters. The application results have shown that the refined processing and integrated interpretation of reservoir parameters can satisfy the requirements of reservoir evaluation and reserves calculation in this oilfield.
