Fractured reservoir prediction is the emphasis and difficulty of current oil and gas exploration��and the key of the prediction is detection of fractured zones�� Based on the attenuation coefficient of qp-��qsh- and qsv waves��the authors study the detection of fractured zones��including the effects of fracture density��incident angle and frequency to the attenuation coefficient of the three kinds of waves through numerical calculation using Hudson theoretical model�� The test of theoretical model indicates that the frequency and fracture density are the major parameteres which affect the attenuation coefficient��and the attenuation coefficient represents prodigious difference when the fillings of fractures are different��which provides a theoretical basis for the detection of fractured zones using attenuation property of qp wave��qsh wave and qsv wave��
