Description

Technical Field

[0001] The invention relates to the fields of petroleum, natural gas and geological drilling engineering, and more particularly to a safe and simple lifting pup joint installation tool. Background Art

[0002] During offshore drilling projects, when using drill collars and directional well tools, it is necessary to install or remove a lifting sub. During this process, a dedicated person must control the winch to complete the connection between the lifting sub and the drill tool. Since the lifting sub generally weighs 80-120 kg, the entire operation requires high requirements for the winch operator, and the process is time-consuming and labor-intensive. The existing method of installing or removing the lifting sub has the following three disadvantages:

[0003] 1. The installation or removal of the lifting section requires the cooperation of at least three people: one person to operate the winch to lift the lifting section; one person to adjust the angle of the lifting section to facilitate the installation or removal of the lifting section; and one person to operate the chain clamp to buckle or unclip.

[0004] 2. During the installation or removal of the lifting short section, the lifting short section generally weighs 80-120kg, which is heavy. At the same time, there are problems with the coordination of the winch operators, which can easily cause abrasions and squeeze injuries to the hands or feet of the people who are making and breaking the hooks. Similar safety injury incidents have occurred on offshore drilling platforms and onshore oil fields.

[0005] 3. Due to personnel coordination and operational reasons, the traditional mode of installation or removal of the lifting short section generally takes about 10-15 minutes. During the BHA assembly process, the lifting short section needs to be installed and removed multiple times. The whole process is time-consuming and affects the overall efficiency of on-site operations. Summary of the Invention

[0006] The present invention overcomes the deficiencies in the prior art and provides a safe and simple lifting pup joint installation tool.

[0007] The purpose of the present invention is achieved through the following technical solutions.

[0008] A safe and simple lifting pup joint installation tool comprises: a base, a lifting mechanism, a lifting pup joint support frame, and a lifting pup joint guide wheel. The base is provided with a lifting mechanism, the lifting mechanism is provided with a lifting pup joint support frame, the lifting pup joint support frame is provided with a plurality of lifting pup joint guide wheels forming a guide wheel group, and the lifting pup joint is arranged on the guide wheel group.

[0009] The lifting pup joint support frame comprises a guide wheel setting frame and a support frame. The guide wheel setting frame is provided with a lifting pup joint guide wheel. Both ends of the guide wheel setting frame are respectively provided with a support frame.

[0010] The lifting mechanism includes a telescopic adjustment frame and a support base. The telescopic adjustment frame is an X-shaped telescopic frame. A support base is provided at each end of the telescopic adjustment frame. The support base is connected to the guide wheel setting frame through the support frame.

[0011] The base is provided with moving wheels.

[0012] There are four moving wheels, and the moving wheels are universal wheels.

[0013] A limit frame is provided on the guide wheel setting frame. The limit frame is provided with two limit grooves with semicircular cross-sections. The lifting short section guide wheels are matched and set in the corresponding limit grooves.

[0014] The number of lifting short section guide wheels is 4.

[0015] The beneficial effects of the present invention are:

[0016] Compared with the existing technology, this solution has the following three major improvements.

[0017] 1. Save manpower. Compared with the traditional method that requires three people to complete the installation and disassembly of the lifting short section, after using this device, one person can complete the installation and disassembly of the lifting short section. At the same time, the whole process is more labor-saving and simpler.

[0018] 2. Safe operation. The simple lifting nipple installation tool is used. No winch is required during the installation process. The lifting nipple is in a stable state, reducing the risk of scratches on the hands and feet caused by shaking or swaying of the nipple during the installation process.

[0019] 3. Save time. Compared with the traditional installation method, the use of simple lifting short section installation tools makes the entire operation process simpler, the operation method is more labor-saving, and the operation efficiency is higher. The traditional installation or disassembly of the lifting short section requires 3 people for 10-15 minutes to complete. After using this tool, generally one person can complete the installation or disassembly of the lifting short section in 5 minutes. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] Example

[0024] A safe and simple lifting pup joint installation tool includes: a base 5, a lifting mechanism 4, a lifting pup joint support frame 2, and a lifting pup joint 6 guide wheel 1. The base 5 is provided with a lifting mechanism 4, the lifting mechanism 4 is provided with a lifting pup joint support frame 2, the lifting pup joint support frame 2 is provided with multiple lifting pup joint 6 guide wheels 1 to form a guide wheel group, and the lifting pup joint 6 is arranged on the guide wheel group.

[0025] The lifting sub-section support frame 2 includes a guide wheel setting frame 21 and a support frame 22 . The guide wheel setting frame 21 is provided with a guide wheel 1 of the lifting sub-section 6 . A support frame 22 is provided at each end of the guide wheel setting frame 21 .

[0026] The lifting mechanism 4 includes a telescopic adjustment frame 41 and a support base 542 . The telescopic adjustment frame 41 is an X-shaped telescopic frame. A support base 542 is provided at each end of the telescopic adjustment frame 41 . The support base 542 is connected to the guide wheel setting frame 21 through the support frame 22 .

[0027] The base 5 is provided with a moving wheel 3 .

[0028] There are four moving wheels 3 , and the moving wheels 3 are universal wheels.

[0029] A limiting frame 23 is provided on the guide wheel setting frame 21 . The limiting frame 23 is provided with two limiting grooves 24 with semicircular cross-sections. The guide wheels 1 of the lifting short section 6 are matched and set in the corresponding limiting grooves 24 .

[0030] The number of guide wheels 1 of the lifting short section 6 is 4.

[0031] The working principle of this utility model is as follows: Figure 1 and Figure 2 As shown, the lifting sub installation tool is adjusted to a suitable height through the lifting mechanism, that is, adjusted in time according to the height of the catwalk machine, so as to facilitate the buckling of the lifting sub 6 with the drill collar; the lifting sub 6 is hoisted to the upper end of the installation tool, and the lifting sub 6 is set on the guide wheel group composed of the lifting sub guide wheel 1. The lifting sub guide wheel 1 is rotated to adjust the direction of the lifting sub 6 so that the docking bolt part of the lifting sub 6 is aligned with the drill collar to improve the success rate of the drill collar buckling; wherein, the docking bolt part of the lifting sub 6 is Figure 2 The location indicated by the mark in Figure 1 After the setting angle of the lifting short section 6 is adjusted, the chain clamp is used to make up the installation, and the shackle operation is just the opposite.

[0032] Furthermore, the lifting mechanism 4 is used to fine-tune the height. This is achieved by adjusting the support angle of the telescopic adjustment frame 41.
