In the next ten years, oil and gas will still be a very important resource. The development level of oil and gas resources depends on the technical level of drilling technology, and the technical level of drilling equipment determines the technical level of drilling technology to a large extent. As the key drilling equipment, the role and status of oil drilling rig in the exploration and development of oil and gas resources is beyond doubt. Therefore, it is necessary to discuss the technical status and development trend of oil drilling rigs.
With the continuous improvement of drilling technology, especially with the continuous promotion and use of large displacement wells and horizontal wells, and the need of offshore deepwater drilling operations, the drilling depth is increasing, requiring the lifting capacity of the drilling rig to increase. With the increase of the lifting capacity of the drilling rig, along with the continuous improvement of the capacity of the devices such as winch, top drive, drilling pump, etc., it will cause continuous breakthroughs in the design and manufacture of the drilling rig, and require continuous improvement of the drilling speed. In order to continuously improve the drilling speed and drilling efficiency and reduce the labor intensity of workers, it is necessary to improve the automatic equipment configuration of the well site, mainly including automatic tools such as iron roughneck, automatic slip, automatic finger beam, power catway, automatic drill pipe box, pipe grabbing machine, etc.
As a form of rapid transfer drilling rig, the towing drilling rig is to realize the overall transfer of each functional block by improving the local structure and increasing the wheeled transfer device and using the traction of the tractor without changing the main structure of the existing drilling rig.
Hydraulic drilling rigs can improve safety and automation, reduce drilling assistance time and relocation time, and improve drilling efficiency. The main rig adopts hydraulic transmission, which has the advantages of small size, simple structure, stable transmission, accurate action, stepless speed regulation in a large range, and easy access to various complex actions. At the same time, it is also equipped with PLC-controlled automatic drilling tool processing system.
Inclined well drilling rig can be used to drill inclined wells from the ground after the derrick is tilted at a certain angle, which is suitable for the development of underground shallow oil and gas resources in densely populated areas, farmland, buildings and so on. Because of its high transportability and high degree of mechanization, inclined well drilling rig has advantages in the exploration and development of inclined or horizontal wells in shallow heavy oil area.
