In oil extraction engineering,influenced by geological factors and mining systems,oil wells inevitably produce mud and sand.After entering the oilfield terminal FPSO,the mud and sand deposit due to a decrease in flow rate,forming oily sludge.According to the current situation of FPSO oily sludge treatment in a certain oilfield in Bohai,the source and composition of oily sludge are analyzed.Based on the special environment of offshore oil fields,the treatment direction of"electric heating and heat exchange+high-frequency demulsification centrifugal fine separation+dosing/flotation,screw and laminated water treatment concentration"is proposed,and the centrifugal treatment process parameters are optimized,in order to provide a reference for the treatment of oily sludge in offshore oilfields.
