在地震处理中,我们面临着确定传播过程中滞弹性衰减对地震信号影响的问题。为了求解这一问题,需要给出近似的充满流体的多孔岩石物理特性。通过在水平层状介质中采集零偏移距垂直地震剖面数据,我们提出了一种有效参数的估算方法。该参数控制了粘弹性介质中波的吸收和散射,对VSP数据进行滤波后,消除了各个界面产生的直达下行波和一次反射波以外的所有能量。该处理流程要求层厚度大于最低限
In seismic processing, we are faced with the problem of determining the influence of anelastic attenuation on seismic signals during propagation. In order to solve this problem, it is necessary to give approximate fluid-filled porous rock physical properties. By collecting data of zero-offset vertical seismic profiles in horizontal layered media, we propose an effective parameter estimation method. This parameter controls the absorption and scattering of waves in a viscoelastic medium. Filtering the VSP data eliminates all the energy other than the direct descending wave and the primary reflected wave generated at each interface. This process requires layer thickness greater than the minimum
