摘　　要：油田注水是对地层能量进行补充最经济、最有效的方法。随着油藏精细化管理水平的提高,根据油藏的地质特点,对油藏进行精细化分层注水,注水井封隔器的密封性就显得尤为重要,将直接影响分层调配的有效开展。目前油田注水常用的有同心配水器和偏心配水器,相应的验封技术有堵塞式验封和直读式验封,两种验封技术各有优缺点,本文对两种验封技术对应的资料进行分析、总结,为后续的验封工艺的改进以及资料应用提供了基础。Oilfield water injection is the most economical and effective method to supplement formation energy. With the improvement of reservoir refinement management level,according to the geological characteristics of the reservoir,the reservoir is refined and layered water injection,the sealing of injector packer is particularly important,which will directly affect the effective development of stratification allocation. At present,concentric water distributor and eccentric water distributor are commonly used for water injection in oilfields,and the corresponding sealing technologies are clogging sealing and direct reading sealing.
