摘要: 油水两相混合流动是集输管路中经常遇到的现象,研究压力变化规律对集输管道的设计和运行有重
要意义。采用VOF模型,在不同含水率和流动速度条件下对油田地面集输管道弯管处的油水两相流进行了数值模
拟。对计算结果进行分析的结果可知,两相流的含水率和流动速度对弯管处的压降有很大影响;弯管内两相流的压
降随含水率的增大而增大;在弯管内壁压力减小的同时速度增大,在外壁压力增大的同时速度减小;增大流速时,高
含水率的油水两相流的压降先减小后增大。

Abstract: The phenomenon of the oilwater two phase mixed flow is often encountered in the gathering and transportation pipeline, and the study of its pressure variation is important for the gathering pipeline design and operation. Using VOF model to simulate numerically the oilwater two phase flow in bend duct of oilfield surface gathering pipe under different moisture content of crude oil and fluid velocity. Through the analysis of the calculation results, it was known that the moisture content of two phase flow and flow velocity has great influence on the pressure drop in bend duct. With the increase of moisture content, the two phase flow pressure in bend duct increases.The elbow inner wall pressure is reduced while the speed increases, the outer wall of the pressure increases while the rate decreases. While increasing the flow rate, the high moisture content of the oilwater two phase pressure drop first decreases and then increases.

Key words: Numerical simulation , Bend duct , Pressure change , Moisture content ,  Fluid velocity
