In fractural area, because the elasticity is heterogeneity, seismic wave absorbed and scattering, the seismic record is more complex. Thus, the Hurst exponent in fractural area is less than in non-fractural one.

在裂缝发育区段，由于地层介质弹性的非均质性及地震波的散射、吸收等使得地震反射序列变得更为复杂，这样，裂缝发育区地震信号的赫斯特指数小于非裂缝发育区。

In conventional seismic data processing, the earth is regarded as prefectly elastic medium.However,the pores of stratum rock often contain fluid. So, when the seismic wave propagates in it, there are energy attenuation and phase distortion related to frequency. Moreover, the attenuation, scattering,and dispersion of high-frequency components are far higher than that of low-frequency components.

常规地震资料处理中把大地看成是完全弹性介质，实际上，地层岩石孔隙中常常含有流体，当地震波在其中传播时要发生与频率相关的能量衰减和相位畸变，且高频成分的衰减、散射和弥散远高于低频成分。
