WebMay 1, 2024 · The pore surface fractal dimension (D S) of HBPRC in gel, capillary, and large pore regions decreases sequentially although it has no physical characteristics in a transition pore region. The incorporation of fibres has an insignificant effect on D S in gel and capillary pore regions; however, it has a reducing effect on D S in the large pore region. WebFeb 12, 2024 · Results show that the pore space occupied by fluids within hydrate-bearing sands is inherently fractal. The area pore-size fractal dimension decreases but the tortuosity fractal dimension changes little with increasing hydrate saturation, and the sum of these two fractal dimensions can be used to predict the volume pore-size fractal dimension.
WebSeveral parameters such as size, shape and orientation of pores have been evaluated. In parallel, the mechanical properties such as fracture toughness and Weibull modulus were directly measured. In order to appreciate the relevance of the use of QIA, the mechanical parameters have also been deduced from the microstructural features, and a comparison …
