井下压力计标定装置的技术建标要求

On Requirements in Technical Standard Build-up of Proving Device of Downhole Pressure Gauge

在勘探开发过程中,确保井下压力计测量的精准是油田获取准确地质压力数据的保证,通过对井下压力计种类和压力计标定装置技术建标的研究,认为,在整个建标过程中要完成建立计量标定的原理框架;计量标准的传递框图;计量标准的测量重复性考核、稳定性考核及总不确定度的分析。

The accuracy of data measured by downhole pressure gauge is the guarantee to obtain accurate geological pressure data in oilfield exploration and development. This paper, on the basis of researching downhole pressure gauge types and technical standard build-up of proving device of pressure gauge, holds that such aspects should be finished as establishing the principle frame for gauge proving and the block diagram of gauge standard, checking gauge standard repeatedly and stably, and analyzing overall uncertainty.
