Outline of Final Research Achievements

In this study, we conducted laboratory experimental studies focusing on 1) deformation induced by chemical osmotic processes, and 2) deformation caused by spatially heterogeneous two-phase flow through porous medium under extremely slow fluid flow regimes. The samples used were argillaceous rocks because these rocks are expected to function for flow barrier in subsurface. For the theoretical analysis, we applied the theory of poroelasticity extended to two-phase fluid flow condition and the theory of semi-permeable membrane behavior of rocks. Then, we developed a model to explain the laboratory experiments, and also developed a numerical simulation code to quantitatively evaluate the rock behavior. Finally, we integrated the laboratory-based, theoretically-based, and numerically-based approaches to discuss rock physical behaviors of argillaceous rocks under extremely slow fluid flow conditions.

Academic Significance and Societal Importance of the Research Achievements

泥質岩は、放射性廃棄物処分や二酸化炭素地中貯留を実現する場合において重要な役割を果たす岩石であると考えられている。これは、泥質岩は、その透水性が極めて小いことから、物質を長期にわたって閉じ込める能力を持つと考えられているからである。一方、そのような岩石においては、一般的な地下流体挙動の理論では取り扱われることが少なかった連成過程(例えば流動に伴う変形や濃度差に伴って発生する流れや変形)が重要な位置づけを持つ場合が起こりうる。本研究は、そのような状況における泥質岩の挙動に関して、理論的体系を構築するとともに、室内実験を通し実際の現象を把握し、数値解析的に評価することを可能にしたものである。
