Abstract：Different sedimentary facies zones have different water absorbing rule during waterflood development and water-drive reservoir is constantly flushed and reformed,which made the sedimentary facies zones,having good physical property of reservoir,more apparent by waterflood reform action and led the interlayer difference in waterflood input wells to gradually become larger.In view of sharpening interlayer contradiction day by day in the later development stage,plugging strong water accepting layer with big channels and triggering weak or unused layer become necessary choice to increase water swept volume and realize replacement of interlayer production in the later development stage.Since lack of quantitative knowledge of big channel in strong water accepting layer,which affect the effect of water flood adjustment.Through study of seepage flow rule of reservoir,the paper presented using the time that adjustment between production and injection well group became effective to compute the pore throat radius of strong water accepting layer in the later development stage and provided the method for computing the breakthrough flow in high permeable strips,which provided a theoretical basis for plugging the strong water accepting layer.
