摘要
在石油开采过程中,要求用于油井参数测量的压力计能长期可靠工作在100℃以上的高温环境。基于此,文章给出了选用先进的高温电子元器件进行硬件设计,以将井下的压力、温度通过传感器采集后,由处理器对采集的温度、压力数据进行处理并存储到存储器,同时通过数据读取接口由PC读取、显示,从而实现对井下压力和温度的采集。该方法设计的压力计可以长期稳定地工作在150℃的高温环境。
In oil exploitation, the pressure gauge for oil well parameter measuring instrument must guarantee its long-term reliability works in high temperature environment over 100℃. On this basis the hardware design with advanced high temperature electr-onic components is provided. After the pressure and temperature signal being sampled by sensors, it would be processed and saved by microprocessor and saved. The stored data is read and displayed by PC through data read port, thus to realize the underground actuation of pressure and temperature data. The pressure gauge designed by the method can steadily work in the temperature of 150 ℃for long period.
