Taking account of mass exchange between macro-fracture and matrix in the micro-fracture system, the multi-medium percolation model with macro-fractures is set up. The simulator for post-frac performance of naturally-fractured formation is developed.
研究的裂缝性油藏渗流介质包括人工压裂裂缝和天然微裂缝、大裂缝及基质,将大裂缝与基质的物质交换在微裂缝系统中加以描述,建立了含大裂缝的多重介质渗流数学模型,研制了裂缝性油藏压裂后生产动态模拟器,结合塔里木盆地塔河奥陶系裂缝性油藏参数,综合研究了天然裂缝、人工裂缝对压裂后产能的影响。
