Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings. The protection scope of the present invention is not limited to the following:

[0038] A coiled tubing traction robot includes a first section, a second section, a third section, a fourth section, and a fifth section arranged in sequence from right to left. The first section and the second section are both It is sleeved on the front central shaft 10, the fourth and fifth sections are sleeved on the rear central shaft 33, and the left ends of the third section are sleeved on the ends of the rear central shaft 33 and the front central shaft 10 respectively. .

[0039] Specifically, the first section includes a front right oblique block 1, a front left oblique block 4, a front support block 2 and a front friction block 3. The left and right ends of the front support block 2 are respectively sleeved on the front left oblique block 4 and On the front right oblique block 1, the f...

Abstract

The invention discloses a coiled tubing traction robot, comprising a first segment, a second segment, a third segment, a fourth segment and a fifth segment arranged sequentially from right to left; both the front segment and the rear segment sleeve a front center shaft, both the fourth segment and the fifth segment sleeve a rear center shaft, and the left and right ends of the third segment sleeve the ends of the rear and front center shafts respectively. The coiled tubing traction robot has the advantages of high integrity level, high safety, high tractive capacity, and high success rate.

Description

Technical field [0001] The invention relates to the field of oil and natural gas development equipment, in particular to a coiled tubing traction robot. Background technique [0002] Horizontal well technology is widely used in the exploration and development of deep, deep sea and complex oil and gas resources. The difficulty of instrument transportation during its application has gradually become the key technology for oil and gas field development and oil and gas storage and transportation. Conventional tubing transportation, pumping transportation, and coiled tubing transportation have problems such as low efficiency, high cost, and coiled tubing buckling deformation when facing horizontal wells, extended reach wells, and directional wells. Therefore, downhole tractors have gradually developed as a new type of transportation. [0003] For downhole tractors, according to different motion modes, they can be divided into: wheel type, telescopic type, crawler type, and impact type....
