摘要: 与 VSP测井求取的地层平均速度相比,用声波速度测井求取的地层平均速度存在着-定的误差。这种误差主要是声波测井过程中的时间累积误差所致。误差的大小与所测井的井况、所测的井段及该井段的地层情况密切相关。因此,在使用声波测井平均速度进行层位标定和时深转换时,必须先对其存在的误差予以校正,才能使之满足日益提高的勘探精度要求。

Abstract: There are some errors between mean velocity of formations obtained from sonic logging compared to VSP logging, which are mainlyresulted from cumulative time errors in sonic logging, and closely related to well condition, wellbore interval and its formation. Therefore, duringhorizontal calibration and time-depth conversion by means of sonic log mean velocity, it is necessary to correct the existed errors in order to meetrequirements of more and more exploratory precisions.
