钢丝绳断丝、截面积损失是起升大绳失效的主要缺陷。现有的起升大绳检测方法存在漏检、检速度慢等诸多不足。作者借助先进检测技术及仪器，对起升大绳进行了检测分析及验证，可知此检测方法可用于起升大绳安全检测。为钻井井架起升大绳的检测提供了一种科学合理快捷的技术方法，具有一定的理论和实际价值。 The loss of wire rope and sectional area is the main defect of hoisting rope failure. Now in the detection method of drilling hoisting line, there are many deficiencies such as leaking, slowing, etc. With the help of advanced detection technology and instrument, the authors have analyzed and verified the hoisting rope. This method can be used to test the safety of hoisting rope. The detection of hoisting rope for drilling rig provides a scientific, reasonable and fast technical method with certain theoretical and practical value.
