摘　　要：介绍了一种研制的八扇区水泥密度-套管壁厚测井仪的结构特点、工作原理及实际应用情况。该仪器采用与俄罗斯引进的八扇区水泥密度-套管壁厚测井仪相同的测井原理,利用伽马射线散射法同时测量套管壁厚、扇区水泥环密度、平均水泥环密度及套管偏心率。该仪器采用遥测编码信号传输方式,能够与通用的生产测井地面系统兼容。通过现场试验及实际应用证明仪器的功能和测量技术指标均已达到引进仪器的水平。The eight - sector cement density and casing thickness logging tool was developed, and its structure characteristics, working prin- ciples and applications were introduced. The principles are adopted same as the Russian CFД-100 logging tool, which use the Gamma ray scattering to detect the casing thickness, the cement sheath density and the casing eccentricity. The Manchester code was applied to transit the logging data to surface equipment, and was compatible with the ground normal logging system. The well site test results show that the function and the measurement technique index of the tool reaches the level of the imported instrument.
