摘要: 在平均速度场研究中很少利用声波测井资料,这是因为声波测井资料本身的缺陷所致。通过对声波漂移值计算、声波漂移校正和声波浅层补偿时间计算,将声波测井资料校正为接近VSP精度,从而可用于平均速度场中对速度谱速度进行标定。应用该方法在XJ地区建立的平均速度场,经两口新井的VSP检查,最大绝对误差为54 m/s,最大相对误差小于2%。

Abstract: Sonic logging has been seldom applied in average velocity field, owing to some limits of data collection and defection of sonic logging. Sonic logging can be adjusted to VSP through drift calculation of sonic logging, drift correction of sonic logging and calculation of compensation time of shallow layer.Therefore acoustic logging is used to correct velocity spectrum in average velocity field. The average velocity field with maximum absolute error of 54 m/s and maximum relative error of less than 2% in XJ area is tested by using VSP of two new wells.

Key words: sonic logging, drift of sonic logging, compensation time of the shallow layer, average velocity field, XJ area
