◆ Max. Hook load 506160lb (2250kN), draw works installed power rating 650HP×2 sets (485kW×2 sets).
◆ Workover depth 24600ft (7500m) (3-1/2" drilling pipe), drilling depth 13120ft (4000m) (4-1/2" drilling pipe).
◆ Provide the functions of drilling rig and workover rig.
◆ Hydraulic driving base can be moved transversely and lengthways. Cluster well operation can also be performed.
◆ Modular and group design, mud tank and subbase are integrative, which save the limited space. The quantity of hoisting modular is little so as to transport easily and install quickly.
◆ Adopt heavy load wide mast. Perform raising, lowering, and telescoping work hydraulically.
◆ Adopt international famous-brand engine and ALLISON hydraulic transmission, Power transmission system is of double engines parallel operation technique.
◆ Draw works and rotary table are driven independently in parallel.
◆ Adopt overhead centralized lines. The lines have different colors according to their different functions.
◆ Operation control system is of centralized operation in drillers room. The important parts have multiple protection functions.
◆ Adopt air control brake as rotary table anti-reverse brake which is installed easily and safely.
◆ Wellhead operation radius is more than 2.0m. Drillers position is suitable and wide-field for the design of enlarging platform surface.
◆ Adopt portable and environmental-protection new material ( glass reinforced plastics, molding grille, etc ) so as to ensure the equipment can be used comfortably and reliably. It should have a good anti corrosion performance. The weight of modular can be reduced.
