摘　　要：胜利油田埕北 2 1-平 1井是 1口重点科研试验井 ,也是国内陆上油田第 1口水平位移突破 30 0 0 m的大位移水平井。实际完钻井深 4837.4m,垂深 2 6 33.91m,水平位移 316 7.33m,造斜点位置 10 0 0 m,最大井斜 93.6°,水平段长 10 0 m,最大狗腿度 41.6°。介绍了固井中存在的技术难点 ,以及固井设计和施工过程中所采取的措施 ,包括套管摩阻分析计算 ,全钢旋流扶正器和单向回压阀等工具的研制 ,水泥浆体系的优选和现场固井工艺过程 ,为今后同类型井提供了借鉴经验。Well Chengbei21-Ping1 of Shengli Oilfield is an im portant scientif ic research experimental well, and the first extended reach well with a horizont al displacement of more than 3000m on land China. It's a well with real bottom d epth of 4837.4m, vertical depth of 2633.91m, horizontal displacement of 3167.33m , KOP at 1000m, maximum hole inclination of 93.6°, horizontal section of 100m , and a maximum dogleg angel of 41.6°. Cementing in the well is difficult, and m any new technologies and tools are applied during designing and field cementing, such as the use of casing friction calculation software, development of hydrocy clone centralizer and non-return back pressure valve, and the optimized cement s lurry systems and field cementing methods, etc.\;
