Description

Technical Field

[0001] This invention belongs to the field of petroleum extraction and oil and gas well maintenance technology, specifically relating to an automatic rotating Gatling gun clip rod device, its working method, and its application. Background Technology

[0002] A drill pipe is a threaded steel tube used to connect the drilling rig's surface equipment to the drilling equipment or bottom hole assembly located at the bottom of the well. The purpose of the drill pipe is to transport drilling mud to the drill bit and, together with the drill bit, raise, lower, or rotate the bottom hole assembly. The drill pipe must be able to withstand enormous internal and external pressures, torsion, bending, and vibration.

[0003] In the process of oil and gas extraction and refining, drill pipes can be used multiple times. Drill pipes are divided into three categories: angular drill pipes, drill pipes, and heavy-duty drill pipes. The connection order is angular drill pipe (1 piece) + drill pipes (n pieces, determined by the well depth) + heavy-duty drill pipes (n pieces, determined by the drill string assembly design).

[0004] During drilling operations, drill pipes need to be lifted for assembly or replaced after long-term use. Currently, the on-site assembly and use of drill pipes presents the following problems: 1. Traditional equipment is too bulky and its weight is unimaginable, commonly known as "clumsy, heavy, and with zero automation"; 2. There are many on-site equipment operators, posing serious safety hazards and making accidents highly likely, while maintenance time is too long; 3. New and old drill pipes are severely damaged during bulk transportation, resulting in unnecessary equipment damage and maintenance costs.

[0005] Therefore, based on the above problems, the present invention provides an automatic rotating Gatling gun magazine-type storage device, its working method, and its application. Summary of the Invention

The two ends of the drill rod located in the turntable storage groove are respectively inserted into the drill rod fixing groove, and the fixing protrusions located on both sides of the adjacent turntable storage grooves pass through the fixing through holes and penetrate the fixing block.

[0012] In this technical solution, the limiting block is a magnetic structure, and the plurality of drill rod fixing grooves are arranged in a straight line on one side of the fixing block.
