摘要

基于文献中提出的针对常规管中气液两相流分层流稳定性的分析

考虑管壁入流对流型的影响

通过公式推导和分析得出了水平管中气液两相变质量流流型从分层流向非分层流转变的准则。通过室内实验研究和预测计算

分析了3种不同的流型转变准则中多个入流流量下管壁入流对流型转变的影响。研究结果表明

实际水平井筒的单位入流流量通常较小

对本地管道单元流型预测的影响可以忽略不计

但是通过不断累积

使得下游管道中流动参数发生变化

从而影响了下游管道单元中气液流动的流型。因此水平孔缝管中气液两相变质量流的流型判别可以采用常规管流型判别准则

但要分段进行。

Abstract

Based on Kelvin-Helmholtz stability criteria for stratified flow in literature

the new criteria of transition from stratified flow to non-stratified flow for gas-liquid flow in horizontal wellbore was developed

in which the influence of wall inflow was considered.Experimental researches and prediction calculations were done in order to analyze how much wall inflow affected transition conditions.The volumetric flow rate per unit pipe length was small

and the influence of wall inflow might be neglected for the flow pattern prediction of local segment unit

but could not be neglected for the flow pattern prediction of downstream segments unit because it changed the value of flow parameters of downstream segments.Therefore

the transition criteria used for normal pipe flow might be directly used for gas-liquid flow in horizontal perforated pipe.But flow pattern prediction calculations should be done segment by segment in downstream units.
