Most oilfields in China are continental deposits, which show great heterogeneity and the deficiency of natural water energy. Nearly all these kinds of reservoirs have to be injected water to keep formation pressure and enhance recovery efficiency. The distribution of remaining oil in reservoir is extremely complicated after years of water injection. The accurate evaluation of waterflooded...
Shale is a fine-grained sedimentary rock. Flow simulation in shale is challenging due to its multiscale porous structure (consisting of nano- to micropores and fractures) and multi-physics gas flow mechanism (including continuum flow, slip flow, transition flow, Knudsen diffusion and surface diffusion) in these pores. The available studies have provided preliminary understandings on the porous...
Various industrial processes involve two-phase flow in porous media. Examples are found in fuel cells, filtration, paper, food, concrete, ceramics, moisture absorbents, and membranes, to name a few. The common practice in modelling flow and transport in such porous media is to employ the concepts,
models, and algorithms developed in geosciences. However, many industrial porous media are...
We present a detailed analysis of a “full physics” simulated drainage-imbibition capillary pressure hysteresis on a packed sphere test case, with particular focus on the fluid displacement mechanisms. The chosen LBM-based flow simulator includes a surface-element boundary scheme to ensure accurate surface treatment and robust handling of arbitrary geometries even in low grid resolution...
