| 摘 要： | 采用Fluent软件对随钻扩眼器控制短节中球座周边流场进行流场仿真，并通过速度流场的分析以及优化前后速度的对比，对扩眼器流道结构进行优化。仿真结果表明，通过采用优化后的球座结构以及球座外滑套结构，能够有效减小流体对球座和球座外滑套内壁的冲蚀，平缓流场。研究结果可为工程上流道结构设计提供一种新的优化思路。

| Abstract: | The Fluent software has been used to simulate the flow field around the ball seat in the control section of a reamer. By analysis of the velocity flow field and a comparison of the velocity before and after optimization, the reamer's channel structure has been optimized. The simulation results showed that using the optimized structure of the ball seat and siting the ball seat outside the sliding sleeve structure can effectively reduce the fluid erosion on the ball seat and the outside sliding sleeve wall resulting in a gentle flow field. These results thus provide a new way of optimizing the structural design of the channel. |
