Embodiment Construction

[0029] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0030] Such as figure 1 , figure 2 As shown, the structure of the device for connecting a drill pipe to stand roots of the present invention is that a stand 7 is fixedly installed on the front side of the drill floor of the drilling rig and beside the gate ramp, and on the ground beside the front ramp of the stand 7 (foundation surface) A catwalk 1 is fixedly installed, and a lifting manipulator 2 is installed in the catwalk 1. A centralizing chuck 4 for centralizing a single drill pipe and a hydraulic tong 6 for turning or tightening are installed in the stand 7 , The lifting block 5 used for lifting the drill pipe and the suspension chuck 8 of the drill pipe; a two-story platform 10 is installed on the derrick of the drilling rig, and an automatic derrick 9 is suspended under the two-story platform 10.

[0031] The centralizing chuck 4, the hydraulic tongs 6,...

Abstract

The invention discloses a device for connecting a drill rod with a three-joint unit. A three-joint unit frame is fixedly arranged beside a ramp of a drilling door; the three-joint unit frame is internally provided with a pair of hydraulic tongs, a righting chuck, a lifting pulley and a suspension chuck; the ground beside the ramp in front of the three-joint unit frame is fixedly provided with a catwalk; the catwalk is internally provided with a lifting manipulator; a drill head frame is provided with a racking platform; and an automatic rigger is suspended below the drill head frame. The invention also discloses a method for connecting a drill rod with a three-joint unit by using the device. By using the device, mechanical operation is realized in the process of conveying the drill rods and connecting three-joint units without using top driving and well head tools, and thus the time is shortened and the drilling efficiency is improved; and besides, workers are not required to work in dangerous areas, so that the labour intensity is lowered and human injuries are avoided.

Description

Technical field [0001] The invention belongs to the technical field of petroleum drilling equipment, and relates to a device for connecting a drill pipe to a root, and the invention also relates to a method for using the device to connect a drill pipe to a root. Background technique [0002] At present, the general method for connecting and standing drill pipes during drilling is: drag the drill pipe from the catwalk along the gate ramp to the drill floor using the wind winch, and rely on the small wind winch and hydraulic tongs to move the single root in the mouse hole. The connection is the vertical root, and the drill pipe vertical root is discharged into the finger beam by the force of the second-story derrick workers. The above-mentioned operation method is severely damaged when the drill pipe is on and off the rig floor. At the same time, multiple people are required to complete it. The labor intensity of the workers is high, and the operation easily interferes with the top...
