海上油田提高采收率的控水技术

根据海上油田采油特点，分析了海上油田控水的迫切性。海上油田产出水主要来源于注入水、边水和底水。为了提高采收率，任何形式的产出水都要控制。海上油田控水技术由注水井调剖技术和油井堵水技术组成，这两项技术都由措施必要性：划断、堵剂选择、堵剂用量计算和堵剂放置工艺等技术组成。海上油田调剖堵水成功的矿场试验说明，海上油田控水技术具有可行性和广阔的应用前景。

Water control technique of enhanced oil recovery for offshore oil field

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.
