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.
