Abstract: To solve the phenomenon of sticking of tool that occurred in the process of drilling a ultra-deep well and extended-reach well, an anti-stall tool is designed. During the axial contraction and extension of spiral spline shaft of the anti-stall tool, The disc spring system plays the role of storage and release energy. For further understanding, the working performance of the disc spring, combining with the working parameters of the anti-stall tool, the load-displacement characteristics, stiffness characteristics and stress characteristics of the disc spring are analyzed. The analysis results show that the mechanical properties of the disc spring can meet the requirements of the anti-stall tool, which providing a reference and guiding significance for optimizing the working characteristics of the anti-stall tool.
