摘　　要：设计出一种水平井新型Φ90恒扭矩钻具,其对钻井扭矩起到一定的调控作用。为了使恒扭矩钻具可以更有效解决钻井过程中的卡滑问题,对恒扭矩钻具中的主要部件碟形弹簧进行优化设计。在常规设计的基础上以组合碟簧储能最大为目标函数,应用Matlab优化工具箱对其进行结构参数的优化设计,优化结果表明,优化后的碟形弹簧储能增加,可以承受更大的转矩,一定程度上降低了钻头的失速,从而提高钻具的使用寿命。A new Φ90 constant torque drilling tool for horizontal wells is designed, which can control the drilling torque to a certain extent.In order to solve the stick-slip problem of the constant torque drilling tool, the disc spring is optimized.On the basis of the conventional design, with the goal of maximizing the energy storage of the disc spring, Matlab optimization toolbox is used for the optimization design of the structural parameters of the disc spring.The results show that the optimized disc spring has more energy storage, can withstand greater torque, reduces the stall of the bit to a certain extent, thus improving the service life of the drilling tool.
