扇区水泥胶结测井仪及信号处理方法

Segmented bond tool and its segmented signal processing method

扇区水泥胶结测井仪器具备常规水泥胶结测井仪器(声波变密度测井仪)的功能,而且能够识别出水泥环径向的局部缺失、微间隙等的固井质量问题,能够提供套管周围全方位的水泥胶结状况,更好地满足固井质量评价。文章阐述了扇区水泥胶结测井的基本原理,重点分析了扇区信号的测井方法和相关的信号处理方法。

The segmented bond tool can not only provide all functions of the acoustic variable density logging tool(CBL/VDL),but also identify cement channels or voids.The segmented bond logging can supply a global scope assessment of the cement bonding around the borehole,therefore it satisfies cement evaluation well.The paper introduces the fundamental principle of the segmented cement bond logging,and analyses the segmented signal processing method.
