介绍了油井井下温度、压力、深度测量仪表的工作原理及基本结构,阐述了检测与传输方式的特点、提高测量精度和传输的可靠性,测量精度与测量时间成正比、远距离传输电缆的分布参数影响等问题.
The working principle and basic structure of measuring instrument for temperature, pressure and depth in oil well are introduced. The characteristics of detecting and transmitting mode are expounded to improve the measurement accuracy and the reliability of transmission. The measuring accuracy is proportional to measuring time and the distribution of long-distance transmission cable Parameters affect other issues.
