Abstract: The increasing water cone is becoming a severe problem in Bohai oilfields with bottom water. The foam was studied based on foam performance by advanced foam scan method; moreover, oil resistance, plugging capacity, capacity of enhanced oil recovery were researched, which supplied optimized parameters for field test. The technology was successfully used in Bohai QHD326 oilfields, and it show good effects of plugging and reducing water cone, which shows a good prospect in offshore reservoirs with bottom water.

摘要： 底水锥进是目前渤海底水油田开发所面临的严峻问题。针对本问题, 通过泡沫扫描方法, 多孔介质内阻力因子测试、 封堵能力评价、 提高采收率评价等手段对泡沫生成、 稳定性、 封堵效果、 抗油性等进行了研究。结果表明, 泡沫有较好的控水效果, 并且确定施工起泡剂质量分数为0. 5%, 气液体积比为2:1。该技术在渤海
QHD 3 2 - 6油田进行了成功应用, 实现了良好的控制水锥效果, 表明该技术具有良好的应用前景。
