Aiming at the problems of lengthy oily wastewater treatment process,large equip-ment area and high operation cost in offshore low permeability oilfields,the wastewater pro-duced in low permeability oilfield has been treated by home-made ceramic functional mem-brane.The results show that there is a large gap in the operation period of the sewage mem-brane treatment at the outlet of air flotation,walnut shell filter and dual-media filter.The operation period of walnut shell filter and dual-media filter outlet sewage membrane treat-ment meets the requirements of stable operation of membrane equipment,the effluent water quality after process optimization meets the requirements for A1 standard of injection water quality of low permeable oilfield.Economic analysis data shows that the optimum technology of water treatment on offshore oil platform is plate separator+air float+walnut shell filter+du-al-media filter+membrane equipment.
