摘要
综合运用PLC控制技术和交流变频调速技术,研制了大直径钻机控制系统,实现了钻机主机(绞车、转盘)精确调速,以及恒钻压和二位式钻压自动送钻等功能。该控制系统具有整体性能先进、适应性强、维护简单、可靠性高等特点,满足大直径钻机成井和复杂地质构造下钻井的需要。
Combining the PLC control technology with AC virable-frequency speed regulation technique, the paper develops the control system of large-diameter drilling rig, and realizes precise regulation of speed of main mechanism （hoisting winch and turntable） as well as automatic drilling with constant drilling pressure and varaible drilling pressure between upper limit and lower limit. The system has the advantages of advanced whole performance, high adaptability and reliability, easy maintenance, which can meet the technical requirements of the large-diameter drilling rig operating in the complicated geological structure.
