摘要

针对传统测井传输方案的不足

设计了一种高温测井信息光纤传输方案。采用TI公司MSP系列低功耗单片机作为井下测控芯片

高温光模块为信号收发器

耐高温光纤为传输介质。上位机不仅能向下发送命令来控制井下钻机和传感器

也可将该链路回传的测井信息（比如温度、压力、电阻值等）显示出来。实验结果表明

该方案不仅能够长时间在高温工作环境下（110℃）实现测井信息的远距离宽带传输（可达2Mbit/s）

而且能够提供灵活的扩展方式

使占用空间更少、重量更轻。

Abstract

In view of the deficiency of the conventional logging transmission systems

a fiber-optic transmission scheme for high-temperature logging information is designed.In the design

a low-power MCU of TI MSP series is employed as the processing chip of the down-hole monitoring system

high-temperature optical modules as the signal receiver and high temperature resistant optical fiber as the transmission media.The host computer can not only send commands to control down-hole drillers and sensors

but also display the logging information

e.g.temperature

pressure

resistance

etc.Experimental results show that this scheme can implement prolonged long-range broadband（up to 2 Mbit/s） transmission of logging information in high-temperature environment（110℃） and offer flexible way of expansion for the system so that it occupies still less room and becomes lighter.
