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.
