顶部驱动钻井装置简称顶驱,是石油钻井工程中采用的一种新型驱动系统。顶驱电控系统是整个顶驱的驱动控制中心,电控系统运行是否可靠,直接影响生产进度和生产安全。为了提高生产效率和减少钻井事故,本文设计了采用软冗余技术的变频调速系统。经钻井公司现场使用后发现,顶驱采用软冗余技术,既提高了钻井效率,又减少了卡钻等钻井事故,达到了很好的效果。
Top drive drilling device referred to as the top drive, is a new type of drive system used in oil drilling engineering. Top drive electric control system is the drive control center of the top drive, electric control system is reliable, directly affect the production schedule and production safety. In order to improve the production efficiency and reduce the drilling accident, this paper designs the frequency conversion velocity modulation system which adopts the soft redundancy technology. After drilling company on-site use found that the top drive using soft redundancy technology, not only improve the drilling efficiency, but also reduce the drilling and other drilling accidents, and achieved good results.
