摘　　要：套管外封隔器与早强油井水泥桨体系配套应用的综合固井工艺技术,在华北二连油田阿南砂岩油藏阿31断块的应用,很好地解决了多年来该高压注水断块油水井固井质量差的技术难题,为阿南及哈南高压注水砂岩油藏油水井固井质量的提高探索出了一条行之有效的途径。建议以后在二连油田阿南及哈南砂岩油藏进行调整井固井时,套管外封隔器以下油层段使用具有早强、低失水、零析水、微膨胀特点的水泥浆体系。Formation pore pressure increases rapidly due to long term of high-pressure water injection in Erlian Oilfield. The pressure is so high that the formation fluid enters into the space between annular and casing, sometimes even flows up to the surface, causing poor cementing job in this area. Cementing technology combining of using external casing packer and cement with properties of early strength, low filtration and minimum inflation was applied in 8 wells in Ang-31 block. It proved to be a successful way of improving the cementing quality in this area.
