The measurement of oil / water two - phase flow is primarily accomplished by the combination of total flow rate and holdup measurement, and at present, the rotator flowmeter is used to measure the total flow rate. since the rotator flowmeter has movable parts, which makes its responsibility behave nonlinearly under poor environment of me under hole whose fluids have very complex and changeful characteristics and affects the measurement precision. what ' s more, the widely used centralized measurement instrumentation meets problems in oil wells characterized with high production or high water cuts
通常油水兩相流測量主要是通過總流量和持率的測量組合來完成的，目前在總流量的測量中主要使用的是渦輪流量計，由於渦輪流量計具有可動部件使其在流體特性復雜多變的惡劣井條件下的響應呈非線性變化規律，影響測量精度，此外，普遍採用的集流型測試儀器在高產井及含水率高的油井中使用也遇到困難，為此，一種新型的適合非集流型點測的測試方法和測試儀器亟待發展和推廣。 -
