Problems solved by technology
[0006] The derricks of the existing coiled tubing equipment are mostly fixed one-piece derricks. Due to the strict requirements on the length and height of the vehicle for road driving, the length of the derrick and the length of the whole vehicle are limited, resulting in the length of the derrick can only be designed It is relatively short, and the shorter derrick can not meet the operation requirements of the injection head well, that is, there is a contradiction between the length of the derrick and the transportation, which seriously affects the popularization and application of self-contained derrick operations

Embodiment Construction
[0051] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0052] Please refer to figure 1 , 2 , 3, figure 1 It is a structural schematic diagram of the folding derrick provided by the present invention when it is in the state before folding; figure 2 It is a structural schematic diagram of the folding derrick provided by the present invention when it is in the folded state; image 3 It is a structural schematic diagram of the folding derrick provided by the present invention in a folded state.
[0053] In a specific embodiment, the derrick body of the folding derrick provided by the present invention is divided into two sections, one section is the basic section 6, and the other section is the folding section 3. Expand or collapse under action.
[0054]Specifically, the basic section...

The invention discloses a folding derrick, which comprises a derrick body and a folding oil cylinder, wherein the derrick body is divided into at least two sections, the two adjacent sections of the derrick body are respectively a basic section (6) and a folding section (3), and the basic section (6) and the folding section (3) are hinged at a butt joint end part; the folding oil cylinder drives the folding section (3) to rotate relative to the basic section (6); and the folding oil cylinder has a state before the folding and a state after the folding: in the state before the folding, the folding section (3) is positioned above the basic section (6) and is parallel to the basic section (6); and in the state after the folding, the folding section (3) and the basic section (6) are in butt joint and are positioned in the same straight line. The folding derrick has the advantages that the whole operation length can be guaranteed; the operation requirements of an injection head are met; meanwhile, the transportation length can be shortened; the passing performance of the whole vehicle is improved; and the road running requirements are met. The invention also discloses coiled tubing operation equipment provided with the folding derrick.
Description
technical field [0001] The invention relates to the technical field of oil and gas exploitation equipment, in particular to a folding derrick of coiled tubing equipment. The present invention also relates to coiled tubing equipment provided with the folding derrick. Background technique [0002] In recent years, with the development of horizontal well and highly deviated well technology, coiled tubing has become a rare and ideal tool for horizontal well and ultra-deep well transportation of downhole tools, well logging and reservoir stimulation in oil and gas well operations. [0003] Coiled tubing has good coilability, and a coil of coiled tubing can reach several kilometers, so it is also called coiled tubing. Coiled tubing operation equipment has the characteristics of pressure operation, continuous lifting, low damage to the formation, small equipment size, With the characteristics of fast operation cycle and low cost, it can replace conventional tubing to complete many...
