利用高频声波测井资料，我们比较了使用两个或三个泰勒级数项(线性和二次模型)来估计速度随深度变化的速度估计方法。然后，我们验证了关于整体传播子的相位因子，哪种方法更准确。对测井数据和每个平均模型的估计旅行时间参数进行了计算和分析。通过对北海测井资料的分析，验证了保留走时参数的速度模型具有较好的精度。
Using high frequency sonic log data, we compare velocity estimation methods that use either two or three Taylor series terms (linear and quadratic models) to estimate velocity versus depth. Then we verify which method is more accurate with respect to the phase factor of the overall propagator. The estimated traveltime parameters are computed and analysed for the log data and for each averaging model. The analysis which is illustrated on well log data from the North Sea verifies that the velocity models which preserve the traveltime parameters have better accuracy than others.
