Detailed Product Description

Features:
1.The rig is applicable to 2800-4500m drilling depth for oil well with 127mm drilling pipe, and 3500-5000m drilling depth with 114mm drilling pipe.
2.AC-SCR-DC power transmission system is applied. Through stepless speed control to drawworks, rotary table and mud pumps, users can acquire expected drilling performance.
3.Grooved drawwork drum with air clutch to shift speed; Disc brake is applied as main hydraulic and auxiliary brake is Eddy current brake or ETN brake.
4.Rotary table adopts independent drive or united drive.
5.Substructure type of sling shot allows mast and floor equipment installed at low height level then raised integrally utilizing drawworks power.
6.Major components of rig are conform to API specifications and allowed to use API monogram.
