摘要
为了掌握不同热处理方式对钻杆螺纹接头抗粘扣性能的影响,对采用调质处理、调质+高频淬火、调质+等离子淬火的钻杆接头按照API RP 7G规定的最大上扣扭矩进行了上卸扣试验。试验结果表明,增加高频淬火和等离子淬火工序并不能改善钻杆接头抗粘扣性能。螺纹接头尺寸精度是影响接头抗粘扣性能的主要因素之一,对钻杆接头螺纹表面进行高频淬火和等离子淬火虽然可以提高接头螺纹表面硬度,但却会使螺纹接头产生变形,最终并不能提高钻杆螺纹接头抗粘扣性能。
In order to master the effect of different heat treatment manner on drill pipe tool joint to influence the capability resisting to galling, the make-up and break-out tests were done for the tempering tool joint, tempering ＋ high-frequency induction hardening tool joint, and tempering ＋ plasma are hardening tool joint in accordance with maximum torque specified in API RP 7G. The test results shows that the thread joint resisting galling capability could not be improved through applying high-frequency induction hardening or plasma arc hardening. The thread dimension precision is considered to be one of most important factor to prevent galling. Although the thread surface hardness could be increased by high-frequency induction hardening or plasma are hardening, it is accompanied by deformation, so that the resisting galling capability of the tool joint could not be improved.
