摘要： 在对地震信号进行连续小波变换的基础上，采用多尺度吸收属性描述地震波在含气性良好的优质页岩中传播时产生的能量衰减异常现象，建立新的页岩气识别方法，并通过理论分析与模型实验证实了该方法的科学性和有效性。将该方法应用到井研—犍为地区筇竹寺组页岩气识别中，获得了与实钻情况较吻合的应用效果。

Abstract: On the basis of continuous wavelet transform of seismic signals, this paper describes the energy attenuation abnormal phenomena caused by seismic wave propagation in gaseous high?quality shales using multi?scale absorption attributes, by which the new shale gas identification approach is presented and verified by theoretical analysis and model experiment in terms of scientificity and effectiveness.The case study of the shale gas identification of Qiongzhusi formation in Jingyan?Qianwei area shows that the applied result is closed to the real drilling data
