摘　　要：云安 2 1井是红家湾潜伏构造上的一口开发井 ,该井的设计井深为 5 70 9m ,但在实钻的过程中 ,由于钻遇断层 ,引起井深增加 ,裸眼段增长至 180 0m ,属于低压漏失层、超长封固段小间隙井尾管固井范畴。介绍固井技术难点 ,固井技术措施、水泥浆体系的优选。The well Yun'an 21 is a development well in HongJiawan buried structure.The design well depth is 5709m.The well depth increased and open-hole section length increased to 1800m because met fault formation in practical drilling process.The cementing of this well belongs to liner cementing of low-pressure leakage?over-length cementing point and small interval.The paper introduces the difficulty,measures and field application of the cementing technology in the well Yun'an 21,as well as the optimization selection of cement slurry system.
