| 摘 要： | 为了使井下压力计能准确录取资料，需要对作为专用计量器具的井下压力计检定装置进行误差分析。计量了采油厂普遍使用的二等标准井下压力计检定装置的几种误差，并在此基础上，给出了计算误差的方法。通过计算，得ＹＵ－６００型活塞式压力计组成的检定装置的误差值。

| Abstract: | In order to record exactly pressure data of downhole pressure gages, it is necessary to analyze errors resulted from a verification device, a specialized metrological instrument for downhole pressure gages. Various errors of the second-grade standard verification device used widely in petroleum production factories are reviewed. A method for calculating these errors is given on the basis of error analysis of the device for the YU-600 piston-type pressure gage. |
