Abstract:

After a long period of water flooding development,The oil and water distribution of high water cut oil field is
becoming complicated. The remaining oil is more scattered and the related geological studies are becoming more specific. The
remaining oil distribution is not only influenced by reservoir physical property ,sand body distribution,structure effect,and
by injection- production well patterns and sand body relation. So,the study of injection-production well patterns and of how
sand body carries on the configuration is the one of the key factors to further enhance oil recovery of the high water cut oil
fields. Taking a fault block in eastern Jidong Gaoshennan as an example,We established the geological model of the fan delta
frontal sand body. After figuring out fan delta subsea distributary channel clearly,the paper studied how distributary channel
and reservoir physical source direction influenced the injection-production well patterns and the well position by Eclipce. So,
the paper put forward injection-production well patterns deployment optimization scheme of fan delta front subsea distributary
channel reservoir.

Key words: fan delta, subsea distributary channel, injection-production well network optimization, remaining oil, reservoir
