Abstract
According to the characteristics of oil production in offshore oil field,the urgency of water control in offshore oil field was analyzed.The water from offshore oil field chiefly comes from injection water,edge water and bottom water.For the enhanced oil recovery of offshore oil field,any forms of production water must be controlled.The technique of water control for offshore oil field is made up of profile control technique and water shutoff technique which include necessity judgment of water control,type selection,volume calculation and injection technology of shutoff agent.The successful pilots of profile control and water shutoff for offshore oil field show feasibility and broad application prospects of the water control technique for offshore oil field.
