Embodiment Construction

[0017] like Figures 1 to 11 As shown in the figure, the present invention is an intelligent manipulator lifting and lowering system of a pressurized workover rig, which adopts a large-scale lifting hydraulic cylinder equipped with a fixed guide column, and is installed on the top of the piston rod, which can rotate 180° in the horizontal direction and rotate 180° vertically. A dual manipulator mechanism with a 90° direction rotation, and a strain gauge pressure sensor for sensing the manipulator pressure, an iron driller system, a hoist manipulator system, and a 400mm position of the load platform on the workover rig to detect the coupling. The open eddy current testing device, the automatic residual liquid collection mechanism and the pressurized workover rig device are installed together, and under the control of the PLC, the unmanned operation of the wellhead can be realized in the process of raising and lowering the tubing.

Abstract

The invention relates to petroleum machines, in particular to an intelligent tripping pipe system for an under-pressure workover rig. The under-pressure workover rig is provided with a rack (1), a tubular column lifting device and an iron roughneck device (2). The iron roughneck device (2) comprises a back-up wrench mechanism (3) and a spinning wrench mechanism (4), and further comprises a coupling detection part used for detecting the coupling positions of oil tubes, a residual liquid collecting device (5) used for collecting discharged oil tube residual liquid, a horizontal and vertical tube state conversion device (6) for the oil tubes, an oil tube lifting device (8) provided with a grabbing mechanical arm (7) and a control device used for controlling all the parts to act. The iron roughneck device (2) is fixed on a sliding table (11) capable of moving front and back in the horizontal direction. The intelligent tripping pipe system for the under-pressure workover rig has the advantages of being reasonable in structural design, convenient and reliable to use, high in positioning precision and high in automation degree.

Description

technical field [0001] The invention relates to petroleum machinery, in particular to an intelligent pipe tripping system using a manipulator for a workover rig under pressure, and is controlled by an intelligent PLC to realize unmanned operation at the wellhead. Background technique [0002] At present, most of the workover operations under pressure in the petroleum industry use traditional hydraulic lifting mechanisms, equipped with a mast-type wire rope lifting system, to carry out the operation of lifting and lowering the tubing, all of which are manually operated on the wellhead site. Even the pressurized workover rigs produced in recent years have only solved the problems of lifting and lowering the oil pipe and preventing the blowout of the oil well. The operations above the ground are still lifted by the mast wire rope and operated manually. Uphole operations often result in the problem of residual fluid spewing out and contaminating the wellhead, as well as blowout ...
