Embodiment Construction

[0018] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings, but the protection scope of the present invention should not be limited thereby.

[0019] refer to Figure 1 to Figure 3 , The composite iron driller and mud blowout prevention box of the present embodiment include: iron driller 11, mud blowout prevention box 12, connecting pin 13, oil cylinder 14 and oil cylinder pin 15. The mud blowout prevention box 12 includes: a box body 21 , a sealing member 22 , a sealing strip 23 and a union 24 .

[0020] Wherein, the box body 21 includes two half-box bodies that cooperate with each other, in this embodiment, it is two half-cylindrical bodies, but it is not limited thereto. Correspondingly, the seal 22 is two half-circular plates mounted on the top and bottom of two half-cylinders. More specifically, semicircular annular seals 22 are installed up and down inside the two semi-cylindrical bodies of the mud bl...

Abstract

The invention provides a composite iron roughneck and slurry blowout prevention box which comprises an iron roughneck, a slurry blowout prevention box and two oil cylinders. The iron roughneck is provided with a clamp jaw, the box body of the slurry blowout prevention box comprises two half box bodies matched with each other, the two half box bodies are symmetrically arranged on the two sides of the front end of the clamp jaw of the iron roughneck and are connected with the two sides of the clamp jaw respectively through connecting pin shafts, the first ends of the oil cylinders are fixed to the two sides of the clamp jaw respectively through first oil cylinder pin shafts, the second ends of the oil cylinders are connected with the two half box bodies respectively through second oil cylinder pin shafts, and the two oil cylinders drive the two half box bodies to rotate around the corresponding connecting pin shafts to open to expose the clamp jaw, or to rotate to close for slurry collecting. The iron roughneck and the slurry blowout prevention box are integrated, the structure is greatly simplified, the total weight and the total occupied space of equipment are reduced, and more safe operation space is saved at a shaft mouth.

Description

technical field [0001] The invention relates to drilling equipment, in particular to a composite iron driller and mud blowout preventer box. Background technique [0002] In the drilling process of land and offshore oil, various iron drillers and mud blowout preventers have been equipped and used, but in the prior art they all use as independent equipment. When pulling out the drill, after the iron driller completes the breakout of the drill pipe, the jaws of the iron driller's tongs need to exit the operating position, and the mud blowout box can only enter this position after allowing enough space to collect the drill that has just been disassembled. Mud coming out of the rod. Therefore, the two kinds of equipment frequently alternately enter and exit during the tripping operation process, and one equipment must exit the operating position and return to the initial position before the other equipment can enter. This makes the operation time longer and the operation effic...
