During the processes of oil exploration, exploitation, refining, tank cleaning, storage and transportation, a large amount of oily sludge is generated due to accidents, leakage, natural sedimentation and the like, and the oily sludge is mainly classified into three types, namely ground oil sludge, tank bottom oil sludge and refinery oil sludge. Because the oily sludge contains toxic and harmful substances such as sulfide, benzene series, phenols, anthracene, pyrene and the like, and some hydrocarbon substances contained in the crude oil have carcinogenic, teratogenic and mutagenic effects, the oily sludge in the oil field is listed as dangerous solid waste (HW08) by the state, is incorporated into dangerous waste for management, and must be subjected to harmless treatment and resource utilization according to the requirements of the solid waste pollution environment prevention and control law and the national clean production promotion law.
The developed technologies for harmless treatment of oily sludge include incineration, solidification, landfill, biological composting and the like, which play an important role in the harmless treatment of oily sludge, but secondary environmental pollution is generated by gas and ash generated by incineration, pollutants in solidified bodies are released to the environment again due to rainwater soaking, the problem that the pollutants leak to pollute soil and underground water after landfill still exists, and the risk of secondary pollution is also generated by volatile organic matters generated in the biological composting process. Therefore, the above-mentioned method for the harmless treatment of the oil-containing sludge is not optimal.

At present, the resource utilization mainly focuses on the recovery of oil products, such as pyrolysis, solvent extraction, thermochemical cleaning, centrifugation, biological method, ultrasonic method, microwave method, etc. Research shows that pyrolysis is the most promising method for recovering oil from oily sludge because of more recovered oil and less residual residues, but the utilization of pyrolysis residues, residues generated by pyrolysis, is rarely reported. At present, a small amount of the waste cement is used for cooperative disposal of a cement kiln, and almost all the waste cement is subjected to landfill treatment, so that not only is the serious secondary pollution hidden danger existed, but also the waste of resources is caused. Finding a high value-added utilization method of oil sludge pyrolysis slag has become a hot point of interest in the petrochemical industry.
