7000m oilfield drilling rig 

Major features:

 

1. The drawworks and mud pumps are driven by "diesel engine + hydraulic torque converter (or coupling with forward gear box) + chain  compounding transmission box/V-belt

 

compounding transmission system", and the rotary table is driven by mechanical system; 

2. The speed change and shifting of drawworks are controlled by pneumatic remote control system; 


3. The main brake utilizes hydraulic disk brake, and the auxiliary brake utilizes electromagnetic eddy brake; 

4. The rig is modularly designed with reasonable layout, good dynamic cooperation and high power efficiency; Independent driller cabin can be equipped optionally; Integral skid system can be equipped optionally;

 

5. The rig is designed and manufactured in accordance with API standards, conforming to HSE spec and API specs. It can be operated from -35 to +50.
