摘要
文章介绍了哈里伯顿公司新一代测井系统LOGIQ的遥测系统及其采用的ADSL(非对称数字用户线)技术原理,QAM调制解调技术原理。分析介绍了调制解调器的工作过程及基本功能;并对遥测系统常见的通讯故障进行了归纳、分析。
This paper introduces the telemetry system of Halliburton's new wireline logging system LOGIQ,together with the ADSL(Asymmetrical Digital Subscriber Loop) and QAM modulation-demodulation technology applied in it.The paper also analyzes the working process of modulation-demodulation,and summarizes the common communications failures of the telemetry system.
