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 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 problem of instrument transportation in the application process has gradually become the key technology of 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, the downhole tractor has gradually developed as a new type of transportation. [0003] For the downhole tractor, it can be divided into wheel type, telescopic type, crawler type, and impact type according to different movement mode...
