摘　　要：定义了一个新的术语—管壁水润高度。在内径50 mm、长40 m的不锈钢水平环道内,利用环形电导探针研究了油-气-水三相管流管壁水润高度的变化规律,分析了折算气速、折算液速以及液相中入口体积含水率对平均管壁水润高度的影响。结果表明:管壁平均水润高度随折算气速的增加均呈指数衰减变化;随入口体积含水率的增大呈Boltman曲线的增长趋势;入口体积含水率φ<50%、折算气速小于2.0 m/s时,随着折算液速的增大出现了水润高度的峰值。当入口体积含水率φ≥50%时,水润高度随折算液速的线性增大(油水比为1:1)过渡到曲线递增变化。A new term WHLw, no dimension water wetting height at pipe wall, was named in the paper. Fluctuation characteristics of WHLw for gas-oil-water three-phase flow was experimentally investigated by use of ring conducting probes in the horizontal stainless steel pipe with 50 mm inner diameter and 40 m length. The influences of gas and liquid superficial velocities and input water cut in liquid on WHLw were analyzed. It was found that WHLw took on the trend to exponential decay with the increase of gas superficial velocity; the increase of WHLw with the increase of input water cut in liquid coincided with Boltman curve. But it＇s change with liquid superficial velocity was very complicated. Under the condition that input water cut in liquid was less than 50%, a peak in WHLw appeared when gas superficial velocity was less than 2.0 m/s. While input water cut in liquid was equal to or higher than 50%, WHLw increased from linear change to nonlinear variation with the increase of liquid superficial velocity.
