讨论了能消除底水锥进的新型双层完井技术的设计、施工及效果。在油水界面之上采油的同时，在油水界面以下采水。应用了数学模拟方法确定射孔的位置和采油、采水速度以防止水锥。该方法目前在美国路易斯安那州北部的ＮｅｂｏＨｅｍｐｈｉｌ油田实施。已有两口井成功应用了该技术，并获得较理想的经济效益
Discusses the design, construction and effect of a new double completion technology that can eliminate bottom water coning. Oil is collected above the oil-water interface and water is drawn below the oil-water interface. A mathematical simulation method was used to determine the location of perforations and oil recovery and water recovery rates to prevent water coning. The method is currently in operation in the NeboHemphil field in northern Louisiana. Two wells have been successfully applied the technology, and obtain better economic benefits
