摘要
用CFD专业软件Fluent对海上油田井下油水分离装置进行模拟仿真,分析了不同参数(速度、黏度、比重)对高含水期油田(含水率90%～95%)大处理量(10～12.5 m3/h)的水力旋流分离器分离效率的影响。结果表明,入口速度由2.08 m/s增大到12.5 m/s时,分离效率由67.9%增大到93.7%;连续相黏度由0.0013 Pa.s增大为0.013 Pa.s时,旋流器分离效率由61.1%降低到21.7%;而当比重由0.8增大到0.95时,旋流器基本失去了分离能力。
The inner flow field in offshore oil with the computational fluid dynamics （CFD） field downhole oil- water separation software Fluent. Different parameters （DOWS） has been simulated （velocity, viscosity, and specific gravity） affecting the separation efficiency of a hydrocyclone with high water-cut （up to 90% -95% ） and large capacity （10 - 12.5 m3/h） were analyzed. The results show that the separation efficiency increased from 67.9% to 93.7% when the inlet velocity increased from 2.08 m/s to 12.5 m/s. The cyclone separation efficiency increased from 61.1% to 21.7% when the continuous viscosity increased from 0. 0013 Pa-s to 0. 013 Pa＂ s. The hydrocyclone lost the ability to separate the oil and water components when the specific gravity was increased from 0. 85 to O. 95.
