摘　　要：高产天然气井在开发过程中,天然气流经弯曲油管时易导致油管柱振动。基于计算流体动力学理论,利用FLUENT对天然气流经弯曲油管柱时的流场进行了数值模拟研究,得出了该处压强、流速分布,其速度、压力发生急剧变化,并产生旋涡,对油管产生冲蚀,诱发了油管柱振动。模拟结果直观形象地提供了流场分布情况,为采气油管的安装设计及气井开采参数确定提供依据。The gas flowing through the bending vitta easily leads vibration in the exploitation of high-yield gas wells.Based on the computation fluid dynamics thoery,the flow properties in curving gas vitta were simulated by FLUENT.The distribution of pressure and velocity were got,which had a sudden changed.Vortex was generated in the corner.These caused the erosion and libration of vitta,which we don t want to meet.The results gave visual image of the flow properties,which could provide some references to design the vitta and selecte exploitting parameters.
