摘　　要：低角度裂缝段具有声波速度低、密度低、高速度比及泊松比的典型特征。针对速度变化影响地震反射特征:相干技术对地震波形相似性判别可初步划分低角度裂缝发育的有利区带;多波联合反演技术利用裂缝段的典型岩石物理特征,在有利区带约束下可进一步寻找泥页岩裂缝储层发育区。The low dip-angle fracture segment with low speed,low density,high velocity ratio and Poisson＇s ratio of typical feature.According to change speed affect the seismic reflection characteristics：coherence technique of seismic waveform similarity can be favorable zone for preliminary classification of low dip-angle fracture development belt;multi joint inversion technique for crack segment of typical rock physical characteristics,in the favorable zone constraints for mud shale fractured reservoir development region.
