摘要: 根据油水两相动量方程以及油相连续性方程,对水平管道油流携水系统特性进行了分析,提出了油流状态为层流时,在剪切作用下水平管道中水相厚度的分布模型,对油流携水系统形成水塞所对应的临界水相厚度以及水相厚度在流动方向上的分布进行了理论分析,并对管径、积水厚度、油相流速以及物性等参数的影响进行了分析。结果表明:临界水相厚度取决于管径、油相流速以及两相密度,其中前两者的影响较大;水相厚度的分布则取决于管径、初始积水厚度、油相流速及物性参数。

Abstract: We analyze the characteristics of the laminar oil purging water system in horizontal tube, according to water and oil momentum equations and oil mass conservation equation,and the water height gradient model was obtained. Both critical water height what denotes the water height corresponding to the onset of a water plug and the profile of oil-water interface are theoretical analyzed. The results show that the former should depend on the pipe diameter,oil superficial velocity and physical properties, among which the pipe diameter and oil superficial

velocity are two main factors. While the latter relies on the residual water volume in horizontal tube, initial of onset of a water plug, the profile of oil-water interface, and the physical parameters.

Key words:

oil purging water, interface profile, water height gradient, critical water height, oil-water stratified flow, water plug
