Technique for Oily Sludge and Sand Processing in Linpan Oilfield

Physicochemistry water dividing-chemical curing method is used and the super strong dewater capacity of the water dividing agent is used to break the network structures of aged oil to separate the most of water from sludge to have an effective phase segregation for the purpose of obtaining enriched concentration of contaminants and absorbent is used for absorption,the perforation is sealed with chemical reaction for the purpose of adverse curing and innoxious processing.The result shows that the process technique is completely suitable for the treatment of oily sludge,which is of great significance to oilfield production and environmental protection.
