Description

Technical Field

[0001] This invention relates to the technical field of storing and transporting drill pipes, and more particularly to a drill pipe storage container. Background Technology

[0002] With the development of the oil drilling and geological mining industries, drill pipes are being used more and more frequently. Traditional drill pipes are bundled in hexagonal packages at drill pipe steel pipe factories using steel strapping. However, at oilfield drilling teams, the hexagonal packages need to be disassembled manually or semi-mechanically, and the sealing plastic caps need to be removed manually or semi-mechanically. The recycling, storage, and transportation of the plastic caps require additional manpower and time.

[0003] To address this issue, Chinese Patent CN106194066B discloses an automated three-dimensional drill rod storage system. This system uses loading rollers to collect drill rods into the frame and arranges the drill rods on each layer of the drill rod rack, facilitating the collection and retrieval of the drill rods.

[0004] While the aforementioned Chinese patent facilitates the collection and retrieval of drill pipes, drilling teams typically operate in the field or at sea, leaving the drill pipes exposed. If the automated three-dimensional drill pipe storage unit were to tip over, the drill pipes could easily fall out. Furthermore, the drill pipes are easily damaged or contaminated during transport due to their exposed state. Additionally, as the drill pipes roll out or into the frame along the loading rollers, they are prone to collisions, leading to damage and increased construction costs. Summary of the Invention
