摘要：

水平气井较直井更难于连续携液，为了研究水平气井连续携液问题，利用可视化水平井气水两相井筒管流模
拟实验装置（垂直段6 m，水平段10 m，倾斜段6 m）模拟水平井气液两相流动，对比观测直井段、倾斜井段、水平井段
的流动型态。实验表明：水平井三井段中，倾斜管段的携液能力最差，所需临界携液流速最大，可将其作为水平气井的
临界携液流速。倾斜管临界携液流量预测模型中，液滴模型和液膜模型是目前被普遍接受的两类模型。为研究倾斜
管连续携液，实验观测不同倾斜角（28°∼72°）条件下流型变化并测试临界携液流速。实验表明倾斜管段液体主要以液
膜形式被携带，从携液机理分析，液膜模型也更为合理；通过实验测得的213 组数据对液滴模型和液膜模型进行对比
分析，发现液膜模型的平均百分误差、平均绝对百分误差及相对性能系数均较小，从计算结果分析，液膜模型也更为
合理。

Abstract:

Abstract：The continuous fluid removal of the horizontal gas well is more difficult than that of the vertical wells. To study
the problem of the continuous fluid removal of the horizontal gas well，we have simulated the gas-liquid two phase flow of
the horizontal gas well with the visual gas-liquid conduit flow experimental device. This device is made up of vertical tubes，
which is six meter high，horizontal tubes at ten meters，inclined tubes at six meters long. Through experiments，we found that，
among the vertical，horizontal and inclined tubes，the capability of liquid-carrying of inclined tubes is the worst. So，the critical
liquid-carrying velocity of the inclined tubes can be used as the velocity of horizontal gas well. Droplet and film model of the
inclined tubes are now widely accepted. We observed the phenomena of liquid-carrying and test the critical liquid-carrying
velocity in different inclined angles，which are from 28° to 72° The experiments show that liquid in the inclined tubes is carried
by film form，not droplet form. From the mechanism analysis，the film model is more reasonable. Contrast the test values with
the calculated values of film and droplet model，we can also find that film model is more reasonable.
