| 摘 要： | 地震波在地下介质中传播时,由于受到衰减影响,导致地震波的高频能量受到损失和相位畸变.而反Q滤波是补偿地层吸收衰减的一个最有效途径.常规的反Q滤波补偿方法一般是针对叠后地震资料进行的,然而,地震波实际衰减过程是沿着传播路径发生的,并受介质的各向异性影响,所以真正的反Q滤波补偿应该在叠前地震资料中进行.利用沿射线路径的波场...

| Abstract: | The propagation of seismic waves in the earth would cause attenuation,by which influence on high frequency energy and phase distortion were induced.The inverse Q filtration was one of the most important methods to compensate the attenuation of adsorption in formation.The conventional inverse Q filtration method was suitable for poststack seismic data.For the prestack seismic data,the reasonable compensation method was performed along the ray path,the actual attenuation of wave occurred along the propagation... |
