Abstract

The invention discloses an offline three-joint unit establishing device. The offline three-joint unit establishing device is characterized in that a three-joint unit frame is arranged on a side of a base of a drilling rig, a manipulator is mounted on the outer side surface of a base of the three-joint unit frame, a hydraulic rack pipe frame is arranged along a longitudinal side or two longitudinal sides of the manipulator, a hoisting tackle, a hydraulic winch and hydraulic tongs are mounted on the three-joint unit frame, and an automatic derrick monkey is arranged on the lower end surface of a racking platform of a derrick. Compared with conventional drilling rigs, the offline three-joint unit establishing device has the advantages that the additional offline three-joint unit establishing device independently has three-joint unit establishing functions under the working conditions that normal well drilling is unaffected, accordingly, the well drilling efficiency can be improved, the well drilling cost can be saved, and oil and gas wells can be early started up in an acceleration manner.

Description

technical field [0001] The invention belongs to the technical field of petroleum drilling equipment, and is capable of establishing roots while a conventional land single wellhead drilling rig is drilling, and relates to an off-line root establishment device. Background technique [0002] At present, when conventional drilling rigs at home and abroad need to establish roots, they have to establish roots in the state of stopping drilling due to the occupation of the traveling crane and wellhead, which greatly restricts drilling efficiency and increases drilling costs. Therefore, when the wellhead is normally drilled, a new set of device is designed, which can independently realize the establishment of roots, that is, the operation of offline establishment of roots. Contents of the invention [0003] The object of the present invention is to provide an off-line root establishment device, which solves the problem that the drilling operation must be stopped due to the occupati...
