摘要
对基于光纤传输系统成像测井技术的井下视频信号采集系统热设计方案进行了分析与优化。首先利用红外热像仪对光纤测井电路系统进行红外扫描,确定电路系统主要热源并得到温度场分布,然后根据红外测试所确定的热源利用热仿真分析软件对光纤测井电路系统进行建模并解算,得到了一定温度下电路系统的热仿真温度场分布。通过对所得到的温度场分布进行分析,对电路系统的结构和低功耗设计进行了改进,提高了整个电路系统的耐温性能。
The analysis and optimization of thermal design scheme of the down-hole video signal acquisition system in video imaging well-logging technology were considered based on the fiber transmission system.First,the electronic circuit system of fiber logging was scanned by infrared thermal scanner to make sure the main heat sources and the temperature distribution was obtained.The simulation model is built for this system based on that main thermal sources to gain the temperature distribution under certain temperature,by analyzing and solving with the thermal simulation software,the distribution is analyzed to improve the structure and power dissipation,the high-temperature performance of the system is enhanced.
