A Study on Flow Unit Model and Distribution of Remaining Oil in Complex Fault Block Reservoir;

The heterogeneity of a reservoir not only exists as common,but also is an important factor that influences waterflood efficiency of waterflood oil reservoir and distribution of remaining oil during the later development period.

Study on remaining oil distribution of Ⅱ1—2 strata of No.437 fault block in Shuanghe oilfield;

Fluvial facies reservoir occupies large proportion of reservoir in our country, but because of its complicated architecture and serious non-homogeneous effect, the effect of the numbers of sandwiches in channel sand body on the distribution of remaining oil has been analyzed, and the cause of its formation discussed.

The performance data,reservoir description and numerical simulation have indicated that the distributary channel sand reservoir is severely waterflooded in area,with its remaining oil only in faults,corners and micro-highs,and that the type II and III reservoirs of mouth bar and distal bar are not perfect in injection and production ,with a greater potential of remaining oil.
