The invention relates to land petroleum drilling machine equipment, in particular to an angle-adjustable well mouth fake rotary plate device for inclined straight wells. A fake rotary plate unit of the device comprises a fake rotary plate, a hydraulic cylinder supporting frame and a fake rotary plate angle index plate are welded to the left side face of the fake rotary plate, a plurality of round holes are formed in the fake rotary plate angle index plate, a hinged lug base is welded to the lower end face of the fake rotary plate, an angle sensor fixing frame is fixed to the fake rotary plate, and an angle sensor is fixed on the angle sensor fixing frame. According to the angle-adjustable well mouth fake rotary plate device for the inclined straight wells, automatic angle adjustment of the well mouth fake rotary plate is achieved, occupied space of the well mouth fake rotary plate device is reduced, the automation degree of the well mouth device is improved, labor intensity is relieved, drilling operation efficiency is improved, and the defects that an existing well mouth fake rotary plate platform is large in size, incapable of automatically adjusting angles and unfixed and inaccurate in angle adjustment are overcome.
Description
Technical field: [0001] The invention relates to equipment for a land oil drilling rig, in particular to a false rotary table device at the wellhead with adjustable angles for inclined and vertical wells. Background technique: [0002] During the operation of the inclined vertical well drilling rig, the wellhead platform needs to be adjusted at different angles according to the inclination angle of the derrick. Due to the large volume of the false turntable platform of the wellhead, the space of the wellhead platform of the drilling rig is limited, and the mass of the false turntable is large. In addition, the adjustment angle It is also not fixed, so a set of automatic angle adjustment mechanism needs to be specially designed. Invention content: [0003] The technical problem to be solved by the present invention is to provide an angle-adjustable wellhead false turntable device for inclined and vertical wells. Reduce labor intensity and improve drilling efficiency. It o...
