Abstract: A great deal of oily sludge has been producedin the crude oil production process in Henan oilfield. In viewof the features of the sludge, through many experimental research of deoiling, dewatering, solidification and combustion, the oily sludge process technology applicable for Henanoilfield has been determined and achieved good effect. Thistechnology realized oily sludge harmless, reducing and available, avoided pollution caused by effluent sludge, and protected the oil region environment effectively.
