导程数、槽深和槽宽等4个结构参数对工具出口峰值速度的影响程度并确定了工具最优结构参数。结果表明,较小的槽深和槽宽、较大的导程和导程数可以起到很好的增速效果。槽深取5mm,糖宽取40-45mm,导程数取3倍,导程取172~219mm时,气液混合物经过涡流工具后气相峰值速度最大,携液效果最好。工具结构参数对工具出口峰值速度的影响程度随气液条件而变化,液气比较大时,选择较大的乎程数具有更明呈的增建效果;入口建度较大时,较小的槽宽具有更明显的增建效累,而较大的导程增速效累并不明显;较小的糖深始终具有明显的增速效果。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。

Abstract: A study was made on structural optimization of swirl tool to enhance operation efficiency of the swirl fluid-discharging and gas-producing tool in gas wells. AutoCAD and Fluent fluid simulation software were used in the study to build a flow field model for gas/liquid in swirl tool. In addition, orthogonal test was performed to clarify the program for simulation and calculation. Through variance and range analysis, impacts of four structural parameters (i.e. lead, number of leads, trough depth and trough width) on peak ve-locity at outlet of the tool were determined together with optimal structural parameters for such tool. The results show that minor trough o a o saoa oea aaaa e ea an e ea e an e d[oo s ao l/s s o a ne a 6 o pea pe o q eoa s o i with the most desirable fluid-carrying capacity can be obtained. Impacts of structural parameters of such tool on the maximum outlet velocity may vary with conditions of gas/liquid. With relatively high liquid/gas ratio, higher number of leads may effectively enhance the velocity. With relatively high velocity at inlet, smaller trough width may obviously increase the velocity. Besides, larger leads may have
