Drill Pipe Scraper (Single‑Layer / Double‑Layer)
Drill Pipe Scraper (Single‑Layer / Double‑Layer)
This product is made of high‑quality wear‑resistant rubber as the base material, with an internal skeleton to prevent deformation.
Main Applications
It prevents drilling fluid from flowing back out of the well, and removes drilling fluid on the outer wall of drill pipes to avoid metal corrosion.
Working Principle of Drill Pipe Scraper
The drill pipe scraper is a multi‑functional scraping device for oil drilling, consisting of a metal recovery tray and a rubber scraping ring. The outer‑wall drill pipe scraper adopts sliding‑way centering scraping plates that slide along the slideways. Driven by double‑acting air cylinders and springs, the scraping plates tightly cling to the annular outer wall of drill pipes being lifted out of the well. They scrape off drilling fluid from the outer wall of the rising drill pipes, leaving the drill pipe columns clean and free of drilling‑fluid pollution to the environment.
The metal recovery tray is fitted with multiple through‑holes for mud recovery, and is equipped with a surrounding baffle to prevent mud overflow outside the well and falling objects from dropping into the well. The pressure plate and bolts are used to fix the rubber scraper. The rubber scraping ring is a replaceable component, which is sleeved onto the drill pipe to scrape mud.
During drilling operations, there was previously no effective solution for removing drilling fluid adhered to the drill pipe outer wall when tripping out. At present, 80% of drilling crews manually scrape off drilling fluid on drill pipe outer walls. This not only increases the labor intensity of rig operators, but also results in incomplete cleaning. Scraped‑off drilling fluid splatters onto the rig floor, creating dirty, slippery and unsafe working conditions, and causing severe drilling‑fluid waste. For this reason, our factory has developed this special scraper for oilfield workover machinery, which effectively solves the problem of removing drilling fluid adhered to drill pipe outer walls.
