摘要：

针对减少流动损失这一工程问题,通过分析油管悬挂器的结构特点,综合考虑其在水下卧式采油树中的位置和功能,基于阻力系数方法提出了油管悬挂器出油口角度的优化设计方法.同时,采用FLUENT软件对不同出油口角度下的油管悬挂器内部流体流动进行数值模拟,为理论设计方法提供证明和依据.最终得到的理论计算结果和数值模拟结果均表明:出油口角度在11°12°之间时流动损失最小.

关键词: 海底管道, 水下卧式采油树, 油管挂, 出油口角度, 优化设计

Abstract:

Aiming at the engineering problem of flow loss, an optimization design method of tubing hanger outlet is proposed on the basis of drag coefficient method, which considers the structural characteristics of tubing hanger, as well as the position and function of tubing hanger. By using the FLUENT software, a finite element model for tubing hanger is developed and the fluid flow in the tubing hanger is simulated. The results obtained by the drag coefficient method and the numerical results show that the best tubing hanger outlet angle is between 11° and 12°.

Key words: subsea pipeline, horizontal tree, tubing hanger, outlet angle, optimal design
