摘要
在分析S71绳索取心钻杆接头结构参数的基础上,建立了其上扣扭矩计算公式。给出了利用ANSYS对钻杆接头进行上扣扭矩影响分析的实现方法。所得结果与实际情况相符,可用于最佳上扣扭矩的计算及钻杆接头螺纹参数的优化研究。
A formula of the make-up torque of S71 diamond wireline coring drill pipe joints was established after the analysis of its structural parameters. The finite element analysis method about the make-up torque of the drill pipe joints with ANSYS was put forward. And the results were consistent with the actual situation, so it could be used in parameter optimization and the proper make-up torque calculation of the drill pipe joint thread.
