Fault-block reservoir is composed of fault-block , it is fault-
screened oil pool , nature energy is not enough and is short of
supplement. Fault2block reservoir is at high water-cut stage
quickly. Exploitation characteristic of fault-block reservoir is
particular at high water-cut stage. reservoir is a serious
heterogeneity reservoir , contrary between layers stand out , the
distribution of remaining oil is not regular , production decrease
swiftly and water cut increase. On the basis of exploitation
characteristic of fault-block reservoir at high water-cut stageand
exploitation practice of some typicalfault-block reservoir , some
effective methods is put forward to enhance developmentefficiency
of fault-block reservoir at high water-cut stage. In this paper ,
some methods and results could be used in similarreservoir.
