我国研制的第一台陆用可控硅直流电驱动钻机,经现场工业性试验证实,其性能仍能与直流发电机—电动机组系统的电驱动钻机相媲美,并能简化机械传动系统。转盘调速范围宽,泥浆的排量和压力容易调节,有助于喷射钻井工艺的发展。
The first land-controlled thyristor DC driven drilling rig developed by our country has been confirmed by on-site industrial tests that its performance is still comparable with that of a DC-electric motor system and simplifies the mechanical transmission system. Turntable speed range, mud displacement and pressure easily adjusted to help jet drilling process development.
