摘　　要：塔河油田奥陶系油藏是经过多期构造运动和古岩溶共同作用形成的岩溶缝洞型碳酸盐岩油藏。利用成像测井资料及双侧向电阻率测井资料识别裂缝和溶洞,是目前测井资料综合解释应用的热点。当储层中存在缝和洞时,电阻率幅度应有不同程度的变化,根据这些变化,能有效的研究裂缝参数。对塔河油田A区B组裂缝性储层进行研究,分析了裂缝倾角、致密碳酸盐岩电阻率、泥浆电阻率、FMI成像测井资料处理参数与双侧向测井响应的关系。Currently Ordovician reservoir of Tahe oilfield in Tarim is the major exploration blocks. It is the karst fractured carbonate reservoir. It＇s the result of the interaction of multi-episode tectonic movement and karst.Along with exploration dynamics unceasing enlargement, the use of image formation log information and dual lateral logging data to identify fractures and caves that become the hot spot in log information integrated interpretation application recently. When the reservoir has the fractures and holes, the electronic resistivity scope should have the varying degree changes. According to these changes, the fracture parameters can be effectively researched. This paper focuses on the research of the fracture reservoir in the Tarim oilfield A area B Group. The paper has analyzed the relationship between the crack inclination angle and the dual lateral well logging; the response relationship of the compact carbonate rock electronic resistivity, mud electronic resistivity and the dual lateral well logging; and the response relationship between the processed parameters of the FMI image log information and the dual lateral well logging.
