Abstract:

For string automatic processing problems of the gear rack drilling rig for slant well, through the top drive and track clamp joint practices, an automated device was devised, which could fulfill the need of the make-up and break-out and spinner action, and hydraulic control system was designed. The bond graph theory was applied to design the bond graph model of the power head spin buckle system and the track clamp system, and the state equations of system were derived from bond graph model. In the 20-sim software, the dynamic simulation analysis was carried out and the simulation parameters of the bond graph element were calculated, the rationality of the model was validated through comparative analysis, which provides technical support and theoretical guidance for the research of the make-up and break-out equipment of the oil drilling rig for slant well.
