Embodiment

[0034] An unmanned operation platform for workover and wellhead, including a workbench 1, a flange 2 is provided in the middle of the workbench 1 for pipe rods to pass through; the workbench 1 is also provided with a hydraulic tong assembly and a push pipe assembly, The hydraulic pliers assembly is used to disassemble and connect pipe rods, the hydraulic pliers of the hydraulic pliers assembly can move radially along the flange 2 , and the pipe push assembly is used to push the pipe rods away from the workbench 1 .

[0035] As a specific embodiment of the hydraulic tongs, the hydraulic tongs include a main tong 3 and a back tong 4. The main tongs 3 are driven by a hydraulic motor 51 to rotate the main tongs, so that the back tongs 4 can hold the female end of the pipe buckle, the main tongs, and the main tongs. The pliers 3 clamp the male buckle end of the pipe buckle, and then the main tongs 3 are driven to rotate by the hydraulic motor 51, so that the male buckle end and the ...

Abstract

The invention relates to the technical field of oil field oil recovery, and specifically relates to a well repair well mouth unmanned operation platform. According to the adopted technical scheme, thewell repair well mouth unmanned operation platform comprises a work table; a flange allowing a pipe rod to penetrate is arranged on the middle portion of the work table; a hydraulic tong assembly anda pipe push assembly are further arranged on the work table; the hydraulic tong assembly is used for detaching and connecting the pipe rod; a hydraulic tong of the hydraulic tong assembly can move inthe radial direction of the flange; and the pipe push assembly is used for pushing the pipe rod away from the work table. By means of the well repair well mouth unmanned operation platform, the piperod lifting and placing work during oil field well repair can be effectively and reliably completed, mechanical and automated pipe rod lifting and placing are achieved, and the well repair well mouthunmanned operation platform has the characteristics of being easy, rapid and safe to operate. In the whole operation process, the position of well repair platform is relatively fixed, it is avoided that the device position is adjusted during each time of well repair, repeatability of the operation is good, and the well repair efficiency is high.

Description

technical field [0001] The invention relates to the technical field of oil recovery in oil fields, in particular to an unmanned workover wellhead operation platform. Background technique [0002] During the normal production process of oil and gas wells, production will be reduced or stopped, and oil and gas wells will be repaired or maintained, collectively referred to as minor repair operations. The basic method of minor repair work is to use the pipe rod as the main means to lift the original tools and pipe rods in the well, and then carry out the construction of the project according to the construction design. After the construction purpose is completed, the repaired tools or pumps are removed through the pipe rod. Run into the predetermined position in the well to restore the normal production of oil and water wells. Downhole operations (minor repair operations) are dirty, hard, tiring, and dangerous jobs with high labor intensity, serious environmental pollution, and...
