摘　　要：介绍了可循环泡沫钻井完井液的配方、性能及在罗 1 5 1 - 1 1井欠平衡压力钻井中的应用情况。在罗 1 5 1 - 1 1井中的成功应用表明 ,该体系密度低、悬浮和携带岩屑能力强 ,抗污染效果好 ,能够满足欠平衡压力钻井的需要 ,且能减少低压油气层的损害 ,对胜利油田低压地层欠平衡压力钻井具有重要意义。The formula, properties and applications of cyclable foam drilling & completion fluids in underbalanced drilling in Luo 151 11 Well are introduced. Successful applications in well luo 151 11 show that this system has low density, powerful capability of suspending and carrying rock cuttings, good results of anti pollution and can meet the demands for underbalanced drilling. Furthermore, this system can decrease the damage on low pressure oil reservoir and will be important for underbalanced drilling in low pressure formations in Shengli Oilfield.
