Abstract Pore network extraction, which is defined as the transformation from irregular pore space to a simplified in form of pores connected by throats, significant microstructure analysis and modeling. A physically realistic not only representation sense topology morphology, but also good tool for predicting transport properties accurately. We present method extract employing centrally located medial axis guide construction maximal‐balls‐like skeleton where throats are parameterized. To...
We have proposed a “simultaneous high ionic conductivity and low surface diffusion barrier” route by fabricating lithium sulfamate layer for Li metal anode. The artificial enabled uniform deposition at rate, thus dendrite was inhibited the interfacial stability enhanced.
Manually annotated corpora are valuable but scarce resources, yet for many annotation tasks such as treebanking and sequence labeling there exist multiple with different incompatible guidelines or standards. This seems to be a great waste of human efforts, it would nice automatically adapt one standard another. We present simple effective strategy that transfers knowledge from differently corpus the desired annotation. test efficacy this method in context Chinese word segmentation...
Jointly parsing two languages has been shown to improve accuracies on either or both sides. However, its search space is much bigger than the monolingual case, forcing existing approaches employ complicated modeling and crude approximations. Here we propose a simpler alternative, bilingually-constrained parsing, where source-language parser learns exploit reorderings as additional observation, but not bothering build target-side tree well. We show specifically how enhance shift-reduce...
Understanding pore-scale oil-water two-phase flow dynamics in reservoir rocks is fundamental for optimizing petroleum exploitation. However, limitations real-time observation have hindered comprehensive characterization of these processes. This study employs a novel three-dimensional visualization platform that integrates online micro-CT imaging (3.78 μm resolution) with displacement experiments Berea sandstone. Experiments conducted at 20 °C and 50 across rates (0.10–0.35 mL/min) revealed...
Food security is a goal and means of global sustainable development, an important component China’s national security. Based on grain production data from 2000 to 2020, 31 provinces (cities, autonomous regions) in China were used as research units analyze the spatiotemporal differences driving forces using combination local correlation index, center gravity transfer model, geographic detector. The results follows, ① During period, total showed decrease followed by increase, yield per unit...
Organic-rich shales have abundant micronanopores and slits. Most exist in organic matter pyrites. Pore size distribution significantly influences shale gas flow. In of pyrites, pore has a self-imitating or fractal property. This property is helpful upscaling calculation. this work, intermingled model for organic-rich investigated. First, on the basis scanning electron microscopy (SEM) images samples Longmaxi formation, units are built-in representative elementary surfaces Second, models...
Abstract Efficient and accurate evaluation of capillary pressure relative permeability oil–water flow in tight sandstone with limited routinely obtainable parameters is a crucial problem oil reservoir modeling petroleum engineering. Due to the multiscale pore structure, there complex nonlinear multiphase sandstone. Additionally, wetting behavior caused by mineral components remarkably influences displacement pores. All this makes predicting extremely difficult. This paper proposes...
Abstract Characterization of shale cores with low and anisotropic permeability is complicated, due to the presence multiscale pore structure thin layers, defies conventional methods. To accurately reproduce morphology core, a novel core-scale reconstructing method proposed reconstruct 3D digital-experimental models by means combination SEM, EDS images, nitrogen adsorption pressure pulse decay experiment result. In this method, multicomponent algorithm introduced build representative model...
Investigating immiscible displacement in fractured porous media is essential for understanding the two-phase flow behavior within pores and fractures. In this work, a three-dimensional pore-fracture network model was developed to address influence of fracture on patterns characterize fracture-matrix crossflow under different conditions. Sensitivity studies at wide range viscosity ratios capillary numbers underscored that significantly influenced fingering zone. Fracture with an advantageous...
Summary Shale possesses abundant micro/nanopores. Most micro/nanopores that exist in organic-rich shale are organic pores and mainly developed matter. The pore distribution matrix space significantly affects gas percolation diffusion. Pore-size a self-similar, or fractal, property. permeability of can be easily rebuilt evaluated, respectively, using fractal theory. In this work, 3D intermingled-fractal model (3D-IFM) is successfully built scalable scanning-electron-microscopy (SEM) images...
