对国外钻机井电系统标准的探讨与实践

针对我国钻机井电系统的通用配置有一定局限性,进入国际高端市场有一定难度的状况,结合中油长城钻井公司进入阿曼钻井市场时钻机井电系统进行整改的实际应用,从供电制式、开关选择、电缆设计、接地保护、防爆及防护要求等诸方面,系统地总结了国际高标准钻机对井电系统的要求,以期为我国今后石油钻机井电系统的设计及安装提供参考。

Discussion and practice of well electricity system of foreign drilling rig

For the certain limit of common configuration of well electricity system of drilling rig and the difficult access to the international high-rank market, in combination with the actual application of the system in Oman drilling market, the requirement of foreign high-rank standard drilling rig on well electricity system is summarized systematically in terms of electricity supplying mode, switch selection, cable design, grounding protection and anti-explosion for providing reference for designing and installing the well electricity system in our country in the future.
