裂缝地层双侧向测井响应物理模拟研究

为了研究裂缝对双侧向测井响应的影响，在实验室建立了一套双侧向测井物理缩比模拟系统。用该系统分别对水平裂缝地层、垂直裂缝地层和斜裂缝地层的双侧向测井响应进行了测量。测量结果表明，裂缝对双侧向测井响应是有影响的，且随着裂缝倾斜角度的变化而变化。

On Scale Modeling of Dual Laterolog Responses to Fractured Formation

Dual Laterolog is a conventional resistivity log which is one of the most widely used methods. It is not only an effective method to distinguish oil from water in shaly sand formation, but also a viable method to detect fractures in carbonate formation. In order to study the effects of fractures on the responses of dual laterolog, a scale modelling system is established in lab. Responses of horizontal, vertical and inclined fractures are measured. The measured results indicate that dual laterolog responses are not only affected by fractures but also change with the fracture dips.
