油氣水多相流在線測量技術(shù)的研究和現(xiàn)場應(yīng)用

介紹了一種新型的油氣水多相流在線測量技術(shù), 它綜合利用多相流流型調(diào)整、互相關(guān)流量測量、雙能伽馬相分率測量、多相流模擬計算、計算機控制和通訊技術(shù)等多種現(xiàn)代檢測和控制技術(shù), 以進行多相流在線檢測; 在流型適應(yīng)性、測量范圍和測量精度等方面的性能有重大改進; 利用該技術(shù)研制的在線測量裝置已通過了國內(nèi)外權(quán)威機構(gòu)在實驗室和工業(yè)現(xiàn)場的測試和檢定, 主要性能指標(biāo)均達到或超過了國外同類產(chǎn)品的水平, 且已在油田現(xiàn)場應(yīng)用多臺。

Abstract　Th is paper int roduces a new in2line technique fo r metering the mult iphase flow of o il?w ater?g as. It in2 tegratedly ut ilizes the state2of2art measuring and cont ro l techniques of mult iphase flow condit ioning, cro ss co rre2 lat ion flow measuring, dual gamma fract ion measuring,mult iphase flow analog computat ion, computer cont ro l and
communicat ion technique etc. to meter in2line the mult iphase flow. It has great ly imp roved on the adap tability of flow regimes,measuring range and measuring accuracy etc. Based on these techniques the mult iphase metering p roduct s have been successfully tested and evaluated by the domest ic and overseas autho ritat ive o rganizat ions. The main specificat ions have come up to and surpassed the levels of the same type p roduct smanufactured by fo r2 eign companies.
