The basic parameters of drilling rig are consistent with national standards GB/T23505-2009 stipulations of drilling rig and workover rig.
DC electric drive drilling rigs adopt international advanced AC-SCR-DC power systerm. The drawworks,rotary table and mud pump can be stepless speed changing so that the drilling rig can aquire good drilling performanceThe drilling rigs adopt parallelogram integral rising substructer to achieve installation of drill floor equipments and mast at a low location.The substructure can be raised in place by drawwork power.
The main brake of drawworks adopts hydraulic disc brake which have enough brake torque and is flexible and reliable. The auxiliary brake is equipped with air-cooling or water cooling electronic eddy current brake. But the auxiliary brake ialso can be pneumatic control disc control. Drawworks are equipped with automatic drilling service for disc brake.
The drilling rig is equipped with independent driller control room.The gas ,electric and hydraulic control and drilling parameters and instrument display 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 teletransmission of the data.Driller can accomplish all operations in the room which can improve the working environment and decrease labour intensity of drillers.
The manufacture of main components accord with API relevant specifications and the components are stamped with API mark.
