The invention discloses a moving drilling machine well repair platform. The moving drilling machine well repair platform comprises a plurality of templates in demountable mode, each template is connected with another template through hinge pins, and accordingly flexibility is stronger. Moreover, the well repair platform is assembled through standard templates, and accordingly transportation is convenient. The appearances of a left main pry, a right main pry, a right auxiliary pry and a left auxiliary pry are consistent, the appearances of a first connecting frame, a second connecting frame and a third connecting frame are consistent, the appearances of a first paving board, a second paving board and a third paving board are consistent, and during mounting, the types of templates are not required to be marked to distinguish. Connecting positions of the templates are respectively provided with limit plates for ensuring collinearness of centers of pin holes, the pin holes are guaranteed to be aligned during assembling, and users only need to directly assemble connecting pins and safety pins. The moving drilling machine well repair platform has the advantages of being simple in structure, convenient to mount, safe, reliable and the like.
Description
technical field [0001] The invention relates to the field of auxiliary supporting equipment for a mobile drilling rig, in particular to a workover platform for a mobile drilling rig. Background technique [0002] In the prior art, when the mobile drilling rig is drilling, the production well often breaks down, and a workover device is usually required for workover at this time. However, if a faulty well is repaired with a large-tonnage mobile drilling rig, resources will be wasted. In response to this problem, we designed a workover platform for workover operations on the guide rails of mobile drilling rigs, used to place workover rigs, stand and workover tools below 120 tons, and provide a place for workover operations and wellhead operations Space; the platform bears the workover load, the lifting load of the workover derrick and the self-weight load of the equipment, and transmits these loads to the foundation or ground through the well site track. Contents of the inve...
