介绍了音频大地电磁测深法在探测修武盆地页岩气目标层黑色泥页岩中的应用效果，利用AMT探测得到的电阻率断面，从深至浅划分了5个电性层，查清了罗洞向斜地层结构和断裂构造的发育特征；根据黑色泥页岩相对围岩的低阻特征，查清了黑色泥页岩目标层的埋深、厚度及展布特征，在罗洞向斜核部，页岩气目标层埋深大约1000 m，目标层厚160～200 m。 AMT探测结果为修武盆地页岩气远景预测及评价、页岩气探井的部署提供了重要依据。

The application effects of AMT in the exploration of shale gas target layer in the black silk shale of Xiuwu basin are de?scribed in this paper. The resistivity section obtained by AMT was divided into 5 layers from the deep part to the shallow part, the AMT explored the development characteristics of the stratigraphic structure and faulted structure of the Luodong syncline. The AMT also ex?plored the buried depth, thickness and distribution characteristics of the black silk shale targets on the basis of the low resistance of the black silk shale relative to surrounding rocks. The buried depth of shale gas targets in Luodong synclinal core is about 1 000 m, and the thickness of the target layer is 160~200 m. The exploration results by AMT provide an important basis for the prognosis and evaluation of shale gas and the well deployment for shale gas exploration in Xiuwu basin.
