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.
