The invention belongs to the field of oil and gas exploitation, and relates to a monocline block spring piece supported coiled tubing traction robot. The monocline block spring piece supported coiledtubing traction robot consists of a front and rear working nippleand a control nipple; the monocline block spring piece supported coiled tubing traction robot is mainly characterized in that the overall structure is symmetrically arranged, the front and rear part is the working nipple, the middle part is the control nipple, and the nipples are tightly locked by bolts;the working nipple adopts a monocline block flexible spring piece structure, amonocline block is pushed through a push rod so that the spring piece is supported anda well wall istightly locked, and the monocline block can adapt todifferent tube diameters and automatically unlocked in case of power failure or resistance; andthe control nipple integrates a hydraulic system and a control system of a robot. Compared with existingtraction robots, the monocline block spring piece supported coiled tubing traction robot has the advantages thatthe gripping effect is good, adaptability of the tube diameter is wide, unlocking is automatic, traction force is large, the structure is simple, the monocline block spring piece supported coiled tubing traction robot can withstand the reverse torque of a drill and is especially suitable for complex downhole conditions.
Description
technical field [0001] The invention relates to the field of oil and gas development equipment, in particular to a coiled tubing traction robot supported by a single inclined block spring leaf. Background technique [0002] With the wide application of horizontal well technology, the problem of difficult transportation of instruments during the operation has become increasingly prominent. In order to solve the difficult problem of downhole instrument transportation, downhole tractor is gradually developed as a new type of instrument transportation tool. So far, downhole tractors have been developed into various types such as wheel type, telescopic type, crawler type, spiral type, and eccentric support type, among which wheel type and telescopic type are the most commonly used in engineering. [0003] Wheeled tractors such as the wheeled tractors of the foreign Welltect Company, the PowerTrac wheeled tractors of the Asker Company, the wheeled tractors of the Sondex Company, ...
