AC VF Drive Drlling Rig 1500-7000m
• Drawworks adopt main motor or independent motor to achieve automatic drilling and make real time monitoring for tripping operation and drilling condition.
• Intelligent traveling block position control has the function of preventing “bumping top and smashing bottom”.
• The drilling rig is equipped with independent driller control room. The gas, electric and hydraulic control, drilling parameters and instrument displays can be arranged unitedly so that it can achieve logic control, monitoring and protection through PLC during the whole drilling. In the mean time, it can also achieve saving, printing and remote transmission of the data. Driller can accomplish all operations in the room which can improve the working environment and decrease the labour intensity of drillers.
• It can be equipped with top drive device.
• It can be equipped with overall moving slide rail or stepping device to meet the requirements for movement between well locations as cluster drilling is conducted.
