Description

Technical Field

[0001] The utility model relates to the technical field of geological core drilling, in particular to a hand-held mud scraper for a logging cable of a geological core drill. Background Art

[0002] In the field of geological core drilling, when recovering the logging cable, it is necessary to clean the mud on the surface of the cable. Usually, the driller uses a cotton cloth to wipe the surface of the cable. As the cotton cloth continuously absorbs water, if it is not replaced in time, it is very difficult to clean the mud on the surface of the cable.

[0003] A patent with the publication number CN219472028U discloses a hand-held drill pipe mud scraper, which includes a mud scraper body and a mud scraper handle; the mud scraper body includes a first clamping arm and a second clamping arm. The front parts of the first clamping arm and the second clamping arm are close to each other to form a reduced-diameter part, and the first clamping arm and the second clamping arm in front of the reduced-diameter part extend in opposite directions to form a horn-shaped front-end guiding part; wear-resistant mud scraping rubber sheets and wear-resistant mud scraping wires are arranged side by side on the inner walls of the middle and rear parts of the first clamping arm and the second clamping arm. The principle of the utility model is reliable and the operation is simple. During the process of pulling out the drill string such as reverse reaming and pulling out the drill string due to drill tool leakage, holding the drill pipe mud scraper at the wellhead can effectively scrape mud and clean the mud or oil stains attached to the outer wall of the drill pipe. At the same time, it can well meet the actual on-site operation requirements for facilitating the movement of the drill string when encountering resistance or sticking during pulling out the drill string.
