页岩气测井评价方法及应用

利用测井资料对页岩气进行评价有两方面的内容,一是页岩的识别,即利用页岩在测井曲线上的异常响应特征,确定页岩层的位置与厚度;二是对页岩气储层进行评价,有机碳（TOC）含量是评价页岩气的重要参数,利用ΔlgR技术,可以快速有效的计算页岩层的有机碳（TOC）含量。实例表明利用测井方法并结合地球化学实验资料,可以对页岩气进行有效评价及预测。

Shale Gas Logging Evaluation Method and Applications

Using logging data to evaluate shale gas has both sides＂ subject matters; the one is shale identification, thus using abnormal response characteristics on logging traces to determine shale location and thickness; the other is shale gas reservoir evaluation, total organic carbon （TOC） is an important parameter to evaluate shale gas, using Alog R technique can estimate TOC in shale layer quickly and effectively. Examples have demonstrated that using logging method combine with geochemical experiment information can carry out shale gas effective evaluation and prediction.
