Abstract: THE DEVELOPMENT OF OIL GAS WATER THREE PHASEMETERING SYSTEMHuang Liguo\ Guo Qingxue\ Qin Peiyou\ Zhang DaminLi Jun\ Liu Yuwen\ Wang Guifeng(Dalian Applied Technique Institute of Nuclear Industry,116032)ABSTRACTThe principle, compose of sofeware and hardware, function and primer result of test in oil gas water three phase metering system are introduced in detail.The metering system developed from crude oil moisture gauge using double low enery radiation can autometer oil gas water in crude oil transmission with online. Accuracy and stabilization can satisfy use of field. The system have been applied in Daqing oil field and Shengli oil field.Key words oil gas water three phase metering system crude oil moisture gauge accuracy stabilization
