Abstract

Abstract:

Small complex fault-block reservoirs with edge and bottom water usually feature in narrow oil-bearing belts,multiple oil layers and large stratigraphic dip and so on.Controlled by structural shape,reservoirs and interbed barrier,the driving mechanisms of edge and bottom water are complicated and have big influences on development effect,making it difficult to determine development mode.We established mathematic and numerical models based on quantification of sealing capacity of interbed barriers.Using numerical simulation,we defined development modes under different conditions of interbed barriers and oil-bearing belt width.For oil reservoirs with strong vertical sealing capacity of interbed barriers and wide oil-bearing belts,layer-by-layer or layer-subdivision production can improve oil recovery.While for oil reservoirs with narrow oil-bearing belts,cross-layer production should be avoided.Oil recovery of layer-by-layer or layer-subdivision production is higher than that of other development modes.However,layer-by-layer production may reduce production rate and separate layer production may increase investment,so commingled production would be more profitable when the oil-bearing belts are narrow.In narrow oil reservoirs,the nearer the producer is to edge water,the lower oil recovery is,so producers should be placed from edge water as far as possible.

Key words: interbed barrier, development mode, reservoir engineering, numerical simulation, small complex fault-block
