[0002] Offshore downhole tools are special equipment for marine engineering surveys and explorations. Their overall appearance is a cylindrical long tube, with a main length of 9m-15m. As offshore operations mainly rely on ship platforms, there are many operating equipment on board, the lifting process of the drilling rig on board is complicated, and the deck space is limited. After the operation of the offshore downhole tools is completed, they need to be placed vertically in a special storage tool.

[0003] Currently, vessels conducting marine operations are equipped with ratholes near the moon pool on the deck. Rathole pipes can be placed in the ratholes to store special marine downhole tools to solve the problem of limited deck space on the vessel and the technical difficulties in lifting the drilling rig on board during operations.

[0004] Since the existing rathole pipes are mainly suitable for marine downhole tools with a length of less than 9 meters, they lack adaptability to marine downhole tools of different lengths, especially those with a length of more than 9 meters; at the same time, due to the use of open seamless steel pipe design and welding technology, when the existing rathole pipe is placed in the rathole, the pipe mouth is flush with the rathole mouth, and the external seawater will soak the entire rathole pipe, so that the entire marine downhole tool will be immersed in seawater when not in use, which will have an adverse effect on the functions of some marine downhole tools.

[0005] Therefore, it is necessary to propose a rathole tube device suitable for storing marine downhole tools to store tools of different lengths. Utility Model Content
