Abstract：

In order to improve the leakage prevention and leakage performance of the plugging tool while drilling, the numerical calculation model of the swirling nozzle of the plugging tool while drilling based on the computational fluid dynamics theory is used to study the influence of nozzle structural parameters on the performance of the plugging tool while drilling.The results show that the impeller lead, the number of blades and the diameter of the nozzle outlet have a great influence on the performance of the swirling nozzle.It is preferred that the relevant parameters of the swirling nozzle are critical to the improvement of the leakage prevention performance of the plugging tool while drilling,and provide a theoretical basis for the optimization design of the plugging tool while drilling.
