Based on the flow mechanism and performance of gas liquid twophase plug flow in oil gas gathering line, a slug unit are divided into both gas slug region with liquid film and liquid slug region.
The void fraction in downward gas oil twophaseflow in vertical tube is measured with the combined method of horizontal downward vertical tube for the two flow regimes(bubbly and slug flow).
采用水平—下降管组合法测量了垂直下降管内油气两相流动在泡状和弹状流下截面含气率的值。
