摘要
在可视化管流实验架上,采用压缩空气和雾化液体作为实验介质,模拟连续携液过程并测试实验参数;采用高速摄像仪捕捉到气流中液滴实际形状——椭球体.实验发现:圆球体模型、椭球体模型计算结果与实验值分别偏差10%,58.3%.分析椭球体受力状态并结合实验数据导出了新的椭球体数学模型,按照新模型计算的结果与7口产水气井生产情况一致.
In pipe flow visualization experiments in the rack,compressed air and spray liquid are used as test media,with liquid in a continuous simulation and testing of experimental parameters;high-speed video camera is used to capture the actual shape of the droplet gas stream—ellipsoid.It was found that：that sphere model and elliptical sphere model give,respectively,a deviation of 10%and 58.3%compared with experiment.This paper analyzes the stress state in ellipsoid and the experimental data are used to build a new mathematical ellipsoid model,and the new model gives results in agreement with water production line of seven wells.
