Abstract

The application discloses a system based on top drive device inclination and a working method thereof, and belongs to the technical field of oil drilling. In order to solve the problem of low dismounting efficiency of the existing top drive and single drill rod, the system based on top drive device inclination comprises a lifting device (1), a lifting and tilting device (2), a top drive trolley (3), a top drive main body (4) and a guide rail (7). The lifting and tilting device (2) can make the lower end of the main shaft of the top drive main body (4) tilt forward. The top drive trolley (3) is hinged to the top drive main body (4), and the top drive trolley (3) can move along the guide rail (7). The system based on top drive device inclination directly aims at the single drill rod in the mouse hole through active tilting of the top drive device, does not need to rely on a pipe handling device, reduces the manual operation demand, improves the automation level, simultaneously improves the stress state of the main shaft and the guide rail, and prolongs the service life of the equipment.
