摘　　要：在油藏调整过程中,水淹层的识别,是保证油藏调整成功的基础。本文通过2003—2006年八区下乌尔组特低渗透油藏调整,利用综合测井、核磁测井等技术对低渗透油藏水淹层识别进行研究,形成了低渗透油藏水淹层识别方法,是调整井投产初期高含水井由近20%下降到4.0%左右,确保油藏调整的顺利实施,共钻加密调整井629口,初期平均产能超过设计产能44%,建产能154×104t。It is critical to identify water flooded layer during the adjustment of reservoir. Here is the research of how to identify water flooded layer of extra-low permeable reservoir through comprehensive well-logging、nuclear magnetic-logging during the adjustment of the P2w1 extra-low permeable reservoir, and develop a way to identify water flooded layer of extra-low permeable reservoir, make the water content of early days’ 20% decrease to 8%, and ensure success of the adjustment of reservoir 629 infill-adjustment wells were drilled totally, the deliverability of early days exceeds design one by 44%, which reaches 156×104t a year.
