光纤通讯系统已经安装在象沼泽、沙漠、海底和飞机这类复杂的环境中,而现在却要把它安装在地壳深处。马里兰州盖舍斯伯格的 Optelecom 公司报导,打算于三月底在深的油井钻孔中安装完利用光纤通讯网络的数据记录系统。据 Optelecom 副董事长 Gordon Gould 说,通常一口井至少由一打(12个)传感器来确定周围的地球构造。这些声学传感器、电导率传感器、闪烁计数器(用于测量由中子引发的放射性衰变)和其他检测器,通常都通过导线传送信号,故处理数据速率通 Fiber-optic systems have been installed in complex environments such as swamps, deserts, seabed and aircraft, and are now being installed deep in the earth’s crust. Optelecom of Gesssburg, Md., Reported that it plans to have a data logging system using fiber optic communications installed in deep wellbores by the end of March. According to Gordon Gould, vice president of Optelecom, at least one dozen (12) sensors are usually used in a well to determine the surrounding Earth’s tectonics. These acoustic sensors, conductivity sensors, scintillation counters (used to measure radioactive decay induced by neutrons), and other detectors, usually carry signals through wires, so processing the data rate
