Conventional seismic exploration is based on the assumption of isotropy,it will be waste lots of usefull informations of long offset,and the precision of stack velocity and interval velocity provided can't meet the need of predicting the pre-drilling pre.
传统地震资料处理通常假设地下介质是各向同性的,这将大量浪费大排列处的地震信息,而且它提供的叠加速度及层速度通常无法满足钻前压力预测的需要。
