Embodiment 1

[0054] Minor workover and workover rig integrated operation system, such as figure 1 It includes a wellhead operation module, a pipe rod delivery module 52, and a pipe rod storage module 53, wherein the wellhead operation module is integrated on the loading vehicle in this embodiment. The wellhead operation module includes a pipe-supporting mechanical arm and a hydraulic pipe rod tong located below the pipe-supporting mechanical arm; the pipe-supporting mechanical arm is used to push pipe rods; The pliers body 40, the outer side of the hydraulic pliers body 40 is fixed with a second mounting plate 42, the driving device 43 is fixed on the second mounting plate 42, and the driving device 43 is used to drive the shift switch 41 in different gear positions Action between them; the top of the hydraulic pliers body 40 is fixed with two second guide plates 50, and the two second guide plates 50 are respectively located on both sides of the notch end of the hydraulic pliers body 40, ...

Embodiment 2

[0056] In the integrated operation system of minor workover and workover rigs, on the basis of Embodiment 1, the pipe supporting mechanical arm includes a linear driving device 21, the driving direction of the linear driving device 21 is horizontal, and the driving end of the linear driving device 21 is connected to the pipe supporting device. Handle 25, the push piece 23 is fixedly connected to the handle 25 of the pipe support, one side of the push piece 23 is open, the open side of the push piece 23 is away from the direction where the handle 25 of the pipe support is located, and the push piece 23 is also included The core bushing mechanism 26 inside, the axis of the core bushing mechanism 26 is vertical, the side of the core bushing mechanism 26 away from the direction where the pipe support handle 25 is located is provided with a semicircular gap 27, and the centering permanent magnet 24 is set under the core bushing mechanism 26 . The linear drive device 21 is a telesco...

Embodiment 3

[0061]In the integrated operation system of minor workover and workover rigs, on the basis of any of the above-mentioned embodiments, the pipe support handle 25 and the driving end of the linear drive device 21 are detachably connected by bolts. The centralizing permanent magnet 24 is fixed inside a magnetic metal block, and the magnetic metal block is fixedly connected with the handle 25 and the pusher 23 of the supporting pipe at the same time. It is convenient to flexibly adjust the connection position of the pipe support handle, and it is convenient to ensure the alignment between the core bushing mechanism and the wellhead according to different well site conditions. The centralizing permanent magnet is isolated and protected by the magnetic metal block, and at the same time, the magnetic metal block will be magnetized by the centralizing permanent magnet, thereby increasing the magnetic field strength and improving the ability to prevent the pipe rod from bouncing back. ...

Abstract

The invention discloses an integrated operation system of a small workover rig. The integrated operation system comprises a well mouth operation module, a pipe conveying module and a pipe storing module. Through work of driving equipment, a gear shift switch is driven to act, the effect of automatic gear shifting is realized, and the problem is solved that in the prior art, gear shifting of a hydraulic clamp has to be controlled through manual operation. Through limiting of a second guiding plate, a pipe is gradually guided into a gap, and it is avoided that since the pipe is not located in the center of a well mouth, the pipe cannot smoothly and automatically enter the gap of a hydraulic clamp body. The pipe conveying module can be perfectly matched with an existing hydraulic elevator without manual operation, the defect is overcome that in the prior art, the pipe can be conveyed to the well mouth from the pipe storing module and conveyed to the pipe storing module from the well mouthwith the help of manpower, and the pipe can be automatically conveyed to the well mouth from the pipe storing module and can be unloaded onto the pipe storing module from the well mouth automatically.

Description

technical field [0001] The invention relates to the field of oil and gas production, in particular to an integrated operation system of a minor workover and workover rig. Background technique [0002] The workover rig is the most basic and main operating tool in the workover operation. According to its operating structure, it is divided into two types: crawler type and tire type. The crawler type workover rig is generally not equipped with a derrick, and its power is good off-road, and it is suitable for construction in low-lying muddy areas. The tire-type workover rig is generally equipped with a self-backing derrick, which has fast walking speed and high construction efficiency, and is suitable for rapid relocation. However, walking and entering the well site are relatively restricted in low-lying muddy areas, rainy seasons, and mud-flooding seasons. Workover rig manufacturers each have their own characteristics and strengths. Due to their large scale and strong strength...
