【摘要】 由于岩石各向异性,相速度的大小和方向与能量速度的大小和方向不同。在均匀各向异性介质中,弹性波以能量角方向向前传播。基于已报道的岩石各向异向性参数,文章计算了岩石各向异性对地震勘探信号的时-深转换关系的影响。计算结果表明:如果忽略了岩石的各向异性,震源-接收器阵列的空间排列和方位不同,造成的时-深转换关系产生的误差的空间分布也就不同。更多还原

【Abstract】 Due to the presence of rock anisotropy,the direction and magnitude of the phase velocity differ from those of the energy velocity.The elastic-wave is propagated in the energy angle direction in homogenous anisotropy media.Based on the rock anisotropy parameters reported,this paper calculates the effect of rock anisotropy on the time-depth conversion relation of seismic data. The calculated results show that if ignoring the rock anisotropy,the space distribution of the created time-depth conversion error is related to the space arrange and orientation of the source-receiver array.更多还原
