Background

The relocation of a petroleum module drilling machine requires the disassembly into tens of modules, which are transported to a target well site and then reassembled. The installation and the lifting of the drilling machine greatly affect the relocation efficiency of the drilling machine. The derrick of the existing oil module drilling machine is mostly in a rotary lifting mode, and the rotary lifting mode comprises the following steps: 1. the derrick and the base are sequentially lifted in sequence by one-time rope threading; but the winch needs to be arranged on the drill floor in a high position, which causes the noise of the drill floor to be large and reduces the available space of the drill floor; 2. the derrick is lifted firstly, the base is lifted after the rope is changed, and the winch can be arranged at a low position; but the process of changing the rope is complicated, resulting in low installation efficiency. Because the winch is arranged at a low position, the noise of a drill floor can be reduced, more space is reserved for automation equipment, and the drilling machine winch is in a low position along with the development of environmental protection and equipment automation.

The translation of the petroleum drilling machine is that after one well operation is finished, part of the petroleum drilling machine is disassembled and then translated to the next caliber of the same well site, and then the disassembly part is assembled and disassembled again. The existing petroleum module drilling machine translates, a large amount of cables need to be disassembled, an electric control room is moved, and then the electric control room is reassembled.
