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QHD32-6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。
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 .
