Abstract: The 8000-meter AC variable frequency (DC) driven drilling rig, with a maximum hook load of 585 tons, is developed according to the drilling characteristics of foothill areas in Tarim Basin. The rig should a hook load of 500 tons when tripping in 273mm-diamater casing pipes. It can be electrically driven in two modes - AC variable frequency electric drive and DC electric drive - and adopts a 48-meter-high K-shaped derrick and a 10.5-meter high swing-up substructure. The winch has a new structure of two gears and four gears with a high performance. Based on the on-the-site industrial test, the rig entirely meets the need for modern drilling service in terms of performance indexes and quality indexes designed for hoisting system, rotating system, control system, power system and cycling system. The rig is superior in drilling deep wells in the foothill areas in Tarim, filling the blank for the well depth between 7000 meters and 9000 meters and perfecting the oil drilling rig family.
