[0002] Oil extraction refers to the act of digging and extracting oil in places where oil is stored. In the process of oil extraction, oil and gas flow from the reservoir into the bottom of the well and then rise from the bottom of the well to the wellhead. At present, when offshore oil is extracted, an offshore oil platform is built on the sea surface to facilitate the extraction of submarine oil. Then, it is necessary to select a reasonable development plan based on the geological storage conditions of the oil field, and complete the oil extraction process through drilling projects, oil production projects, and oil and gas gathering and transportation projects. In the process of oil extraction, it is usually necessary to use drilling tools to drill holes in the formation to facilitate the extraction of submarine oil. However, in the prior art, after the existing drilling tools used for oil extraction are used, it is generally necessary to clean the stains on the drill bit to facilitate the storage and later use of the drill bit.
