摘　　要：分层注水技术是解决油藏层间矛盾,提高水驱波及程度,改善水驱开发的有效手段,在油田开发工作中占有极其重要的地位,分注井验封则是保证分注有效性和作业施工质量的重要手段之一,X区块同心双管分注和波码通信分注共计92口,占比72.4%,本文结合管柱结构和现场实际验封情况,针对同心双管分注系统总结出放空验封法、打压验封法和吸水指数曲线法,同时对波码通信分注验封原理分析和实际应用效果评价。Stratified water injection technology is an effective means to solve the contradictions between reservoir layers,improve the spread degree of water flooding and improve the development of water flooding,which plays an extremely important role in oilfield development.The sealing of separated injection wells is one of the important means to ensure the effectiveness of separated injection and the quality of operation and construction.There are 92 concentric double pipe divided injection and wave code divided injection in X block,accounting for 72.4%.In this paper,based on the structure of pipe string and the actual field sealing conditions,the cavitation sealing method,pressure sealing method and water absorption index curve method are summarized for the concentric double pipe injection separation system.Meanwhile,the principle of wave code injection sealing inspection is analyzed and the practical application effect is evaluated.
