井下涡流工具结构参数优化

涡流工具的作用是将气液进行分离,气液分离效果越好,涡流工具作用效果越好,为了提高气井涡流工具排液采气工具的工作效率和使用效果,进行了涡流工具的结构参数优化研究。运用SolidWorks和Fluent流体模拟软件,建立了涡流工具气液两相流场模型。从液相分布、切向速度、轴向速度三个角度分析螺距、导流叶片高度、内径、导程倍数、叶片数对涡流工具作用效果的影响,通过正交试验分析最优的涡流工具参数组合。结果表明,当涡流工具参数为：内径54mm、螺距200mm、叶片高度20mm、1倍导程、单叶片时,涡流工具作用效果最好。研究结果可以为现场涡流工具的优选和使用效果的提高提供依据。

Structural Parameter Optimization of Downhole Vortex Tool

The role of the vortex tool is to separate gas and liquid. The better the gas-liquid separation effect, the better the effect of the vortex tool. In order to improve the working efficiency and use effect of the gas well vortex tool drainage and gas extraction tool, the structural parameters of the vortex tool were optimized the study. Using SolidWorks and Fluent fluid simulation software, a gas-liquid two-phase flow field model of a vortex tool was established. The effects of pitch, guide vane height, inner diameter, lead multiple, and number of vanes on the effect of the vortex tool were analyzed from three angles: liquid phase distribution, tangential velocity, and axial velocity. The optimal eddy current tool parameters are analyzed through orthogonal experiments combination. The results show that the vortex tool works best when the parameters of the eddy current tool are: inner diameter 54 mm, pitch 200 mm, blade height 20 mm, 1 lead, single blade. The research results can provide a basis for the optimization of field eddy current tools and the improvement of the use effect.
