Petroleum drilling machine achieving continuous motion of tripping in and tripping out and method for continuous motion of tripping in and tripping out

Abstract

The invention discloses a petroleum drilling machine achieving continuous motion of tripping in and tripping out. The petroleum drilling machine comprises a top driving lifting mechanism and a rotating disc lifting mechanism. According to the structure of the rotating disc lifting mechanism, the left inner side and the right inner side of a derrick are each provided with a rotating disc guide rail, each rotating disc guide rail is provided with a tackle and a set of rotating disc beam guiding mechanism, and each tackle is located above the corresponding rotating disc beam guiding mechanism; each tackle is downwards hinged to an end head of a piston rod of an oil cylinder, and a cylinder body of each oil cylinder is fixed to the derrick; a fixed pulley on each tackle is wound with a rotating disc lifting rope, one end of each rotating disc lifting rope is downwards fixed to a drilling machine base, and the other end of each rotating disc lifting rope is fixed to a rotating disc beam; and the two sets of rotating disc beam guiding mechanisms are fixedly connected with the two sides of the rotating disc beam correspondingly. The invention further discloses a method for continuous motion of tripping in and tripping out. The petroleum drilling machine achieving continuous motion of tripping in and tripping out is compact in structure, the method for continuous motion of tripping in and tripping out is reliable, and efficiency of continuous motion of tripping in and tripping out is high.

Description

technical field [0001] The invention belongs to the technical field of petroleum machinery, is applicable to onshore and offshore drilling rigs and workover rigs, and relates to a continuous motion jacking and tripping diamond oil drilling rig, and also relates to a continuous motion jacking and tripping method. Background technique [0002] During the tripping process of a conventional oil drilling rig, when a vertical column is lifted, the drill string is supported by elevators or slips and rests on the turntable, the drill pipe joint connecting the vertical column and the drill string is removed, and the vertical column is discharged to the On the second floor platform, lower the top drive (or hook), and after the top drive (or hook) is lowered to the set height, the top drive (or hook) lifts the drill string and removes the elevator from the center of the wellhead of the turntable (or Slips open), the drill string can continue to be lifted. After the female joint at the ...
