速度多用曲线模型及其应用

首先指出地震资料处理和解释中所用速度直线模型及圆弧空校方法存在的严重不足，提出以速度多用曲线模型代替直线模型，以射线跟踪空校方法代替圆弧空校方法的解决办法，给出了多用曲线模型的建立过程。适应性分析表明，该模型拟合精度高，适应力强．最后给出了应用实例，证明这一模型和方法的优越性．

Multi-Purpose Velocity Curve Model and its Application

Serious defects of velocity straight line model and arc spatial correction in processing and analysing seismic data are pointed out. It is suggested that the straight line model and arc spatial correction method should be replaced by the multi-purpose velocity curve model and spatial correction of reactive rays tracing respectively. The setting up procedure of the curve model is presented. Adaptability analysis shows that the model has high fitting accuracy and good adaptability. Application example is also given to show the advantages of the model and the method.
