1 .电驱动钻机钻机是大功率、多工作机联合工作的重型机械。在石油天然气工业中钻机起着重要作用。然而传统的机械钻机机械传动系统复杂、能耗大、效率低、自动化程度低、手工操作繁重、工业卫生条件差。随着石油工业的发展 ,深井、超深井增加 ,钻采技术日趋复杂 ,传统的机械钻
Electric Drilling Rig Drilling rig is a heavy machinery with high power and multiple working machines. Drilling rigs play an important role in the oil and gas industry. However, traditional mechanical drilling rig mechanical transmission system is complex, high energy consumption, low efficiency, low degree of automation, heavy manual operation, poor industrial hygiene. With the development of the petroleum industry, the deep and ultra-deep wells increase and the technology of drilling and production becomes more and more complicated. The traditional mechanical drilling
