Abstract

Abstract: Since high moisture content is one of the characteristics of oil field in China, an oilwater two phase homogeneous flow model was established in this study. Finite volume method and pressure velocity coupling PISO algorithm were adopted to conduct the numerical simulation of oilwater two phase flow in Ttube. The influences of different diameter ratios on the internal local resistance of Ttube were studied. The distributions of pressure and velocity in the Ttube were accessed through calculation. The results indicated that on the intersection of the main pipe and branch pipe, local resistance was the highest, which was obviously higher than the frictional resistances before and after the intersection. Different diameter ratios had great influence on local resistance loss on the intersection. With the increase of vertical branch pipe diameter, local resistance loss increased accordingly. In addition, since the volume of main pipe became larger after the confluence, the frictional resistances were all larger than those before the confluence.

摘要： 针对我国油田含水率较高的特点, 建立油水两相均质流模型。采用有限体积法, 压力速度耦合P I S O 算法对T型管内油水两相流动进行数值模拟, 研究不同管径比对T型管路内局部阻力的影响。经计算得到 T型管路内压力、速度的分布情况。结果表明, 局部阻力最大的位置在主管和支管交汇处, 明显大于交汇前后的摩擦阻力, 而且不同管径比对交汇处的局部阻力损失影响很大, 随着垂直支管管径的增大, 局部阻力损失会相应增大。此外, 由于交汇后的主管流量大于交汇前的主管流量, 交汇后的摩擦阻力均大于交汇前的摩擦阻力。
