含砂流在石油工业中较为常见,是引起设备失效和材料破坏的重要原因之一。引起的这些故障可能导致不可预测的停工和风险,严重影响油井的正常生产。利用FLUENT软件对较易产生磨损的90曘弯管含砂油流流动情形进行了模拟,得到了不同流速下含砂油流在管内的压力场、速度场分布规律,以及管壁处磨损量的分布规律,得出不同速度与冲蚀角对磨损量的影响,此结果可为油品安全输运、流动参数控制及管线磨损防护提供一定的参考依据。

Sand-bearing oil flow is very common in petroleum industry.It is one of the main reasons forequipment failure and material damage,which may cause unpredictable shutdown and risk,seriously embarrasing normal production.The FLUENT software was used t0 SImUlate Sand-beaYlng O11 flow In900 bend pipes which are more likely to be wore.Characteristics of pressure and velocity fields of sand-bearing oil flows with different velocities as well as abrasion volume at pipe wall were put forward.Therelationship between abrasion volume and velocity,erosion angle was found out,providing referencesfOY Safe tYanSpOYt Of O11,control of flow parameter and prevent of pipe.
