Description

Technical Field

[0001] The utility model relates to the technical field of oil drill pipes, in particular to an oil drill pipe cleaning machine. Background Art

[0002] Oil drill pipe is a steel pipe with threads at the tail end, which is used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or bottom hole device at the bottom of the well. The purpose of the drill pipe is to transport drilling mud to the drill bit and raise, lower or rotate the bottom hole device together with the drill bit. The drill pipe must be able to withstand huge internal and external pressure, twisting, bending and vibration. In the process of oil and gas extraction and refining, the drill pipe can be used many times. The drill pipe is divided into three categories: square drill pipe, drill pipe and heavy drill pipe. The connection order is square drill pipe + drill pipe + heavy drill pipe. The classification of drill pipe, drill pipe joints, drill pipe specifications and steel grade and strength of drill pipe are introduced in detail.

[0003] For example, the Chinese patent with patent number CN216655633U proposes an oil drill pipe cleaning machine. The patent places the oil drill pipe to be cleaned on the top of the block. When the hollow pipe is located inside the oil drill pipe, the personnel move the hollow sleeve block. When the locking screw is connected to the lower positioning screw hole, the top of the guide rod is clamped in the positioning groove at the bottom of the hollow sleeve block, which is convenient for positioning the hollow sleeve block. At this time, the water inlet pipe at the top of the hollow sleeve block is located at the lower side of the bottom end of the water pipe. The vertical displacement slide drives the pressure pump and the water pipe to descend during operation, so that the water pipe is inserted into the water inlet pipe, and the drive motor is turned on. When working, it is convenient to drive the first electric chuck to rotate in the second annular sleeve block, thereby facilitating the driving The hollow pipe rotates, and the booster pump is turned on at this time. The liquid inlet pipe of the booster pump is connected to an external water source. After the booster pump pressurizes the water during operation, the water is transported to the hollow sleeve block through the water pipe, and then enters the hollow pipe from the hollow sleeve block, and finally sprayed out through the water spray holes on the periphery of the hollow pipe, so that the cleaning machine can conveniently use the rotation to drive the cleaning structure to rotate on the inner side of the drill rod to be cleaned, and the uniform effect during cleaning is good. However, in this scheme, since the inner wall of the drill rod is cleaned through the hollow pipe, when the staff needs to clean the outer wall of the drill rod, the drill rod needs to be taken out and cleaned again. At this time, the cleaning process of the drill rod needs to be performed twice, which may reduce the cleaning efficiency of the drill rod.

[0004] For example, the Chinese patent with patent number CN212597676U proposes a petroleum drill pipe cleaning device, which supports the drill pipe through a slide, and structurally clamps the drill pipe stably on the top of the slide with a semi-arc pressure plate, and drives the roller brush to rotate through a motor, and then cleans the inner wall of the drill pipe. The entire inner wall of the drill pipe can be cleaned at the same time, saving cleaning time and greatly improving its cleaning efficiency. A bearing is embedded and installed in the support seat. When the end of the roller brush away from the motor passes through the bearing and is rotatably connected to its inner ring, the roller brush can be effectively supported by the support seat, and will not affect the rotation of the roller brush driven by the motor. Both ends of the roller brush are supported, which greatly improves the stability of its structure. However, in this scheme, since the inner wall of the drill pipe is cleaned by the roller brush, when the staff needs to clean the outer wall of the drill pipe, the drill pipe needs to be taken out and cleaned again. At this time, the cleaning process of the drill pipe needs to be performed twice, which may reduce the cleaning efficiency of the drill pipe. Utility Model Content
