摘要
页岩/致密油气藏等非常规油气藏的储层介质为典型的多尺度空间:既具有纳微米级的基质孔隙,又具有微米-厘米级的天然裂缝,以及大规模压裂所产生的米级到百米级的人工裂缝.本文针对裂缝多孔介质,介绍基质、天然裂缝、宏观裂缝及大尺度缝洞中的流体耦合流动数学模型.
Abstract
Unconventional reservoirs,such as shale/tight oil and gas reservoirs,are typically multi-scale spaces with both nano-and centimetre-scale matrix porosity,micrometre-to-centimetre-scale natural fracture systems and metre-to-hundred-metre-scale man-made fractures result-ing from large-scale fracturing.In this paper,we present a mathematical model of the cou-pled fluid flow over matrix,micro-fractures,macroscopic fractures,and large-scale fracture cavities in fractured porous media.
