一种裂缝性油藏岩石物理模拟方法的建立

Development of a Physical Simulation Method of Factured Reservoir-type Rock

阐述了一种获得符合裂缝性油藏地下特征岩块的人工造缝技术。通过模拟该类型油藏岩石成缝机理 ,利用拉伸和单、三轴压缩试验 ,监测体应变或渗透率变化 ,来控制岩心上生成裂缝的方向、大致缝宽和数量。研究该项技术 。

A man made fracture technique accorded with the feature of fractured reservoir type rock is put forth in the paper.Through the fracturing mechanism simulation,the tensile testing and uniaxially or triaxially compressed testing,body strain and permeability variation are monitored to control fracture direction,width and quantity.The technique is useful to the development of lab analysis technique of low permeability fractured cores and reservoir exploitation.
