目前,我国钻井钢丝绳换新是以钢丝绳在一个扭矩上断丝多少为依据的,若钢丝绳使用时间很长,但磨损均匀,没有断丝、断股现象,那就仍可继续使用。当井继续加深或打捞作业中受冲击负荷时,就可能造成断绳,发生顿钻事故。这是我国目前钻井钢丝绳换新标准的最大缺点。若如一些国家用钻井钢丝绳工作的吨公里数标准来切旧,换新,就不存在上述问 At present, the new drilling wire rope in our country is based on how many broken wires the wire rope has on a torque. If the wire rope is used for a long time, it has even wear, no broken wires and broken stock, so it can still be used continuously. When the well continues to deepen or salvage operations by the impact load, it may cause broken rope, drill accident occurred. This is the biggest shortcoming of the standard of drilling wire rope renewal in our country at present. If some countries used the standard of ton-kilometers of drilling wire rope to cut the old ones and renew their new ones, there is no such question
