Abstract: In this paper a summary and classification have been made on the develop ment adjustment for a water-flooding sandstone reservoir,and three fundarnental principles at its high water-cut stage are put forward:(1) Cambinine the hydradynarnic method ii}ith the EOR method,ciopending mainly on the former.(2) Combining well pattern regulari}ation with an elaborate division of formation,depending mainly on the forme:.(3)Combining the "formation-dredging" with the "forrnation-plugging",depending maimy on the former.

摘要： 本文对注水砂岩油田的调整方法进行了总结和分类,并提出了注水砂岩油田高含水期调整的三条基本原则:(1)水动力学方法与提高采收率方法相结合,以水动力学方法为主;(2)井网规则化与细分层系相结合,以井网规则化为主;(3)“疏”与“堵”相结合.以“疏”为主.
