Abstract

The invention discloses a semi-trailer independent type under-pressure well repairing operation machine which comprises a motor tractor, a hydraulic power unit, an under-pressure operation device, an automatic well head aligning device and a semi-trailer chassis. The front end of the semi-trailer chassis is connected with the motor tractor. The hydraulic power unit is installed at the front half portion of the semi-trailer chassis. The automatic well head aligning device is installed at the rear half portion of the semi-trailer chassis. The under-pressure operation device is installed on the top of the automatic well head aligning device. The semi-trailer independent type under-pressure well repairing operation machine can better adapt to conditions of different regions, roads and well fields and is better in maneuvering performance, meanwhile, an independent automatic well head aligning system can adapt to different well head devices, and the preparing time before operation is greatly saved.

Description

technical field [0001] The invention relates to the field of petroleum machinery, in particular to a semi-trailed independent pressurized workover machine. Background technique [0002] With the development of oilfield workover technology, the demand for workover equipment is increasing, and the pressure workover equipment does not need to vent the downhole pressure, which greatly saves the entire operation time, and its application is gradually increasing. Ordinary snubbing workover operations require the use of workover rigs, snubbing devices, trailers, cranes, generator sets and other equipment, which are assembled and connected on site to realize snubbing workover operations. The disadvantage of this method of operation is that there are many auxiliary equipment and the on-site assembly and connection time is long. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention proposes a semi-trailed independent pressurized worko...
