【摘要】 在利用CBL-VDL测井资料进行水泥胶结评价时,地层波能量是反映第二界面水泥胶结好坏的主要标志。文章采用一种类似于地震处理中使用的相似算法,检测地层波的波至,计算地层波到达时间,从而提取地层波首波能量;重点阐述在进行相关对比前,对原始波形的积分变换以及积分函数的设计方法。更多还原

【Abstract】 When using CBL-VDL logging information to carry out cement bond evaluation,formation wave energy is major sign to reflect the second interface cement degree.This paper adopts a similar algorithm that used in seismic processing to detect wave arrival of formation wave and calculate the wave arrival time,and then extracting head wave energy.Focal point in this paper is integral transformation and integral function design for original waveform.更多还原
