钻杆螺纹疲劳试验可以为钻杆螺纹参数设计提供试验依据,因此具有重要意义。本文介绍了国内首次对绳索取心钻杆螺纹进行疲劳试验所用装置及试验有关参数的确定和计算方法,可供今后进一步完善试验参考。
Drill pipe thread fatigue test can provide experimental basis for the design of drill pipe thread parameters, so it is of great significance. This paper introduces the equipment for the fatigue test of the cord coring drill pipe and the method of determining and calculating the relevant parameters for the first time in our country, which can be used to further improve the test reference in the future.
