The invention provides a method for scraping mud on the inner wall of a drill rod. According to the method, a mud scraping device with an anchoring mechanism is adopted for scraping mud on the inner wall of the drill rod. The anchoring mechanism is arranged on the mud scraping device and can measure the mud scraping distance of the mud scraping device and fix the mud scraping device on the inner wall of the drill rod in a braking mode. The method comprises the following steps that a drill rod lifting device is arranged on a drilling platform and used for lifting a drill rod; the mud scraping device is placed in the drill rod and falls down to conduct mud scraping operation; when the stroke assembly detects that the mud scraping distance reaches the set distance, the anchoring assembly brakes and fixes the mud scraping device; after the lifted drill rod is detached, the drill rod is lifted again, the anchoring assembly relieves the brake, and the mud scraping device falls again to conduct mud scraping operation; the steps are repeated until mud scraping is completed, and the mud scraping device is taken out. The mud scraping device has the beneficial effects that the mud scraping device falls to scrape mud on the inner wall of the drill rod through the gravity of the mud scraping device, the mud scraping distance can be monitored, and the falling risk does not exist.
