摘　　要：中伊朗盆地Kashan区块Aran油田第三系库姆组为一套基质孔隙度和渗透率低,且裂缝发育的裂缝性碳酸盐岩储层。钻探取心和成像测井资料观察是了解储层天然裂缝是否发育最可靠、最直接的方法,但成本昂贵。在利用常规测井方法识别裂缝时,双侧向测井具有较强的聚焦能力,它对于探测高阻层裂缝特别有效。该文在前人对双侧向测井响应的数值模拟及反演方法研究的基础上,建立研究区裂缝性储层参数解释模型来估算库姆组C4亚段裂缝参数,并将结果与岩心、成像测井、试油资料对比验证,表明该方法较为准确地评价了研究区裂缝性储层。The Tertiary Qom Formation of the Aran Field, located in the Kashan Block of Central Iran Basin, is a set of fractured carbonate reservoir with low matrix porosity and permeability. For the study of fractured reservoir, the drill core and imaging logging data are the most straightforward and credible means to discern the development situation of natural fracture in the reservoir, but these are expensive. In the traditional logging methods, the Dual Lateral Logging （DLL） is of stronger competence of convergence, it is very useful to recognize the fractures in the resistive formation. On the basis of previous studies on the numerical model and inversion methodology of dual laterolog response, we establish an interpretation model of fractured reservoir parameters to estimate the fracture parameters of sub-member C4 of the Qom Formation in this block, and then compare the results with the core, imaging logging data and well testing data. The result indicates that this method can exactly evaluate the fractured reservoir in this area.
