摘要
扇区水泥胶结测井仪器作为目前检测固井质量的有效仪器之一,能够很好地识别窜槽、水泥局部缺失等固井问题,可以直观详细地评价第一界面的水泥胶结情况。本文介绍了100KHz扇区仪器的信号传输技术,重点阐述了扇区信号调制原理,采用幅度调制技术很好地解决常规电缆对扇区高频信号的有效传输问题。
The sector cement logging tool can availably identify annular bypass, fracture, the partial loss of cement and evaluate in detail cement bond conditions in the first interface of the casing, as one of the effective logging tool to detect cementing quality. This paper introduces the transmission technology for 100 KHz sector signal and mainly describes the sector signal modulation principle, the experiment data prove that it's a practical method to solve the problem of the effective transmission of high-frequency sector signals in common cable by applying amplitude modulation technology.
