摘　　要：以大庆长垣西部地区萨、葡油层为例, 将测井理论与统计分析方法相结合, 从区域构造及沉积特征出发, 利用钻井取心资料系统地研究了储层裂缝与岩石电阻率、岩性密度、补偿中子及井径等测井曲线的关系, 采用测井响应差异分类方法总结出适合该区储层裂缝解释模型。通过取心井及成像测井资料验证, 该模型可以满足油田开发需要。This paper takes Saertu and Putaohua reservoirs of West Placanticline region, Daqing oilfield as examples. From regional structure and sedimentary characteristics,it studies systematically the relation between reservoir fracture and rock resistivity,lithology density,compensatory neutron and caliper curves by means of combining logging theory with statistical methods,drilling core data,and summarizes fracture interpretation models applied to reservoir of the area using logging responses difference sort method. The models can satisfy oilfield development by the verification of core and image logging data.
