摘要:
为了解涡流工具同时携液携砂时流体的流动规律、压力分布、携液携砂效率、影响因素以及工作特性,对流体在涡流工具中的流动进行仿真模拟。对不同结构参数螺旋叶片的槽宽和槽深进行了组合,并对其作用效果进行仿真模拟,得到了涡流工具同时携液携砂的优化结构模型。分析了不同入口速度、气液比、砂粒直径下涡流工具对固相和液相的携带作用。结果表明:气井出水有利于气井携砂,气井含砂会影响涡流工具对液体的离心作用,但对气井的携液能力影响不大; 相同工况下,液体更容易被携带流出; 入口速度越大气井携液效果越好,入口速度变化对气井携砂的作用呈不规律变化; 涡流工具可以降低气井携带固液两相的临界流速; 砂粒直径越大涡流工具对固体和液体的携带作用均越小。
Abstract:
In order to study the fluid flow law,pressure distribution,liquid carrying efficiency,influencing factors and working characteristics of a vortex tool carrying liquid and sand,the flow of the fluid in the vortex tool in a gas well is simulated. For the spiral blade part of the vortex tool,the groove width and groove depth of different structural parameters are combined,and the effect is simulated. An optimum structure model of the vortex tool carrying liquid and sand is obtained. The influences of different inlet velocity,gas-liquid ratio and sand diameters of the vortex tool on the solid phase and liquid phase are analyzed. The results show that the effluent of the gas well is beneficial to the sand carrying,and the sand-bearing of the gas well affects the centrifugal effect of the vortex tool on the liquid,but has little effect on the liquid carrying capacity of the gas well; the liquid is carried out more easily under the same working conditions; the larger the inlet velocity is,the better the fluid carrying effect is,and changing inlet velocity effects the sand carrying of the gas well irregularly; the vortex tool can reduce the critical flow rate of the solid-liquid two-phase carrying of the gas well; as the diameter of sand increases,the carrying effect of the gas well on solid and liquid decreases.
