本文根据波在倾斜地层中的传播理论,提出在大倾角情况下的三维非规则测线速度分析方法。计算结果表明,本方法比一般水平迭加速度分析方法有明显的优越性,它可以在三维地震勘探可能遇到的各种界面倾角情况下,提取速度参数。

Based on the theory, wave propagates through the tilted strata, the method of 3-D irregular line velocity analysis (on condition that the dip is steep) is put forward. From the initial calculation we can see this method is far more advantageous than the conventional horizontal stack velocity analysis. The velocity parameters can be picked up even in the case of having different interface dips while performing the 3-D seismic survey.
