动态轴向水力载荷是影响涡轮钻具止推轴承工作寿命的主要因素之一。针对动态轴向水力载荷特性研究存在的不完善性，从微团动力学平衡和转子动态水头出发，导出了涡轮钻具动态轴向水力载荷特性的实用计算公式，从而为研究新型涡轮钻具和更科学地预估止推轴承寿命提供了初步的理论依据。
Dynamic axial hydraulic load is one of the main factors affecting the service life of the thrust bearing of the turbine drill. In view of the imperfection of the research on the dynamic axial hydraulic load characteristics, a practical formula for calculating the dynamic axial hydraulic load characteristics of the turbine drill was derived from the kinetic equilibrium of the micelles and the dynamic head of the rotor. Therefore, More scientifically predicted thrust bearing life provides a preliminary theoretical basis.
