摘要

根据波动方程的理论, 构造了一种用于叠前资料的成像算法, 使叠前地震资料经过DMO(叠前部分偏移)之后进一步成像, 从而得到等价于叠前全偏移的结果。本文在理论上给出了该算法的运动学和波动理论解释, 并构造了其具体实现算式。

Abstract

Based on the wave theory, an imaging algorithm is construeted to perform further imaging for prestack data after DMO processing (prestack partial migration). As a result, an equivalence of full prestack migration is aequired. This paper presents the prineiple of the algorithm in kinematics and the wave theory as well as its formulation for practice.
