摘要
探讨了层状介质中由时间确定速度、深度的模型 ,给出了相应的共反射段相干反演方法。数值模拟结果表明这种方法精度较高 ,抗噪性能强。对荆江松滋口的部分浅层反射资料处理与现有资料吻合 。
In this paper, a velocity depth model is constructed for layered media. Based on the model, a common reflecting segment based coherence inversion method for determining velocities and depths from seismic data is derived. Numerical modeling shows that the method is characterized by higher precision, better stability, and smaller error accumulated among layers. The results obtained by applying the method to the shallow reflection data from Songzikou of Jing River are comparable with the existing information, indicating that this method is promising.
