description The invention relates to a low-fluorescent-oil-based lubricant for a drilling fluid based on reclaimed oil and derivatives thereof, which is prepared through the following steps: (1) an esterification process and (2) a fluorescence disappearing process. The lubricant has favorable biodegradability and lubrication property, high oxidation resistance, excellent high-temperature-resistant lubrication property and low florescence level, and is less prone to cause fluid loss.
