During the process of oil extraction and treatment, a large amount of oily sludge is generated, which has certain economic value. Improper treatment not only endangers the environment and human health, but also causes waste of resources. Based on the analysis of the physicochemical properties of oil sludge, this article elaborates on the application scope, advantages and disadvantages of methods such as biodegradation, solidification treatment, mechanical centrifugation, solvent extraction, and pyrolysis from two aspects: harmless treatment and resource utilization of oil sludge. It also explores the development path and direction of harmless treatment, resource utilization, and engineering of oil sludge from the perspectives of safety and economy, providing certain reference suggestions for subsequent oily sludge treatment.
