Workover depth 6500 m (21320 ft) (3-1/2" DP)
Drilling depth 3000 m (9840 ft) (4-1/2" DP)

Hydraulic driving base can be moved transversely and lengthways. Cluster well operation can also be performed.

Adopts heavy load wide mast. Performing raising, lowering and telescoping work with use of hydraulic mechanism.

Diesel engine and ALLISON hydro mechanical transmission.

Power transmission system adopts double engine parallel operation method that allows to perform work both with one or two engines so as to enchance efficiency and reliability.
Operation control system is located in the drillers room. Main parts have multiple protection.

Rotary table has forward and reverse gear mechanism. It also adopts a rotary table anti-reversing unit used to prevent drilling string from reversing at a high speed as well as to avoid accidents.

Design of the whole rig meets HSE requirments.

Workover depth 7500 m (24600 ft) (3-1/2" DP)
Drilling depth 4000 m (13120 ft) (4-1/2" DP)

Hydraulic driving base can be moved transversely and lengthways. Cluster well operation can also be performed.

Adopts heavy load wide mast. Performing raising, lowering and telescoping work with use of hydraulic mechanism.

Diesel engine and ALLISON hydro mechanical transmission. Adopts double engine parallel operation method.

Drawworks and rotary table are driven independently and parallel.

Operation control system is located in the drillers room. Main parts have multiple protection.

Adopts modern air-control brake EATON 225DP100, that works as rotary table anti-reverse brake.
Wellhead operation radius is more then 2.0 m. Drillers position is sutable for wide view of the platform.
Rig is build with the use of portable and environmentally driendly construction materials (such as, glass reinforced plastic, molding grille and others). Thus comfortability, reliability, improved anti-corrosion properties and reduced weight of modular blocks are ensured.
