| 摘 要： | 单一的常规测井方法识别裂缝具有一定的局限性，但综合分析各种测井信息，可以总结出常规测井对储层裂缝的响应特征。根据岩心观察和常规测井曲线的资料对比可以发现，深层系储层裂缝的存在使储层电性响应特征之间有明显幅度差，且可以根据这种幅度差建立与裂缝密度之间的一定关系，从而利用常规测井资料计算地层的裂缝密度。

| Abstract: | Though it is unreliable to identify fractures with single conventional log,it is always possible to establish response patterns on conventional log suite that are related to fractured reservoir.Observations on core and conventional logs indicate that the presence of fracture in deep reservoir results in amplitude difference of reservoir electric responses.And a relation between the amplitude difference and fracture density can be established and used for calculation of fracture density from conventional logs. |

| Keywords: | conventional log low porosity low permeability reservoir identification of fracture response fracture density |
