摘要
主要从理论上分析说明二维地震资料处理中速度分析在处理中的运用不足, 指出地表低速带纵横向速度变化不均匀, 岩性变化较大的地区如何正确运用速度分析以减少交点的相位时差, 借以提高复杂岩相横向变化地区的二维地震资料处理效果, 提高时间剖面的处理质量, 对第三纪盆地探区的资料处理具有实际指导意义
The insufficient application of speed analysis to the two dimensional seismic data processing is mainly analyzed and interpreted in terms of theory. And how to apply the speed analysis to the area with the uneven variation of longitudinal and transversal speed in the surface low speed zone and more variation of rock characters to decrease the phase time difference of intersection, raise the effect of two dimentional seismic data processing in the area with complicated transversal variation of lithofacies and the processing quality of time section are pointed out, which are significant in the practical direction of the data processing in the exploration area of Tertiary basin.
