Quantitative characterization of heterogeneity shale nanopores and its influencing factors are significant impact on the occurrence quantity, pore size, mobility oil. 25 Chang 7 samples were analyzed for geochemical properties, mineral composition, FE-SEM, NMR. Combined with multifractal theory, characteristics structure studied, reservoir classification was carried out. The results show that: types include microfracture, intercrystalline pores, intergranular intragranular dissolved pores...
The nuclear magnetic resonance T2 spectra of low-permeability reservoirs with complex wettability were studied using the samples from Chang 8 Member, Upper Triassic Yanchang Formation, Ordos Basin, China. Abnormally high resistivity and normal core selected. NMR under different water saturation conditions, contact angles Amott indexes designed tested. test results show that fully brine-saturated condition, reflect surface relaxation water, while abnormally exhibit wide unimodal spectrum,...
Pore structure determines the ability of fluid storage and migration in rocks, expressed as porosity permeability macroscopic aspects, pore throat radius microcosmic aspects. However, complex strong heterogeneity make accurate description tight sandstone reservoir Triassic Yanchang Formation, Ordos Basin, China still a problem. In this paper, mercury injection capillary pressure (MICP) parameters were applied to characterize structure, three types divided, from high low quality defined Type...
In the field of industrial inspection, accurate detection thread quality is crucial for ensuring mechanical performance. Existing machine-vision-based methods internal defect often face challenges in efficient and sufficient model training samples due to influence geometric features. This paper introduces a novel image acquisition structure, proposes data augmentation algorithm based on Generative Adversarial Networks (GANs) effectively construct high-quality sets, employs YOLO achieve...
Water injection is one of the most common methods used to enhance oil recovery reservoirs with low permeability and strong heterogeneity. However, water in production process, formation salinity, saturation, distribution residual reservoir are altered, causing difficulties evaluation flooded layers. Consequently, it crucial understand changes resistivity when evaluating waterflooded layers different wettabilities. Resistivity experiments for high-resistivity (HR) normal-resistivity (NR)...
Analyses about multiple energy networks are required to explore the increasing interactions among different subsystems. In this work, flow computation of heat and electricity studied. Firstly, a steady state model for multi-energy is established. Then, an alternating iterative method proposed, where subsystems analyzed individually. Moreover, coupling patterns network compared. For each pattern, designed. Test results validate feasibility proposed method.
The relationship between resistivity index and water saturation (I-Sw) is very important in formation evaluation via petrophysical data. Low permeability complicated pore structure make it more difficult to determine I-Sw through rock's electrical property measurements. Nuclear magnetic resonance (NMR) logs are alternative ways obtain these key parameters. To establish a model estimate from NMR logs, 17 cores the study area were selected for experiments. helium porosity, air permeability, T2...
Magnons, the quanta of collective spin excitations in magnetically ordered materials, have distinct properties that make them uniquely appealing for quantum information applications. They can ultra-small wavelengths down to nanometer scale even at microwave frequencies. provide coupling a diverse set other excitations, and their inherently gyrotropic dynamics forms basis pronounced non-reciprocities. In this article we discuss what current research challenges are integrating magnetic...
Abstract The first wear process is running-in, which a stage of each machine system must go through. friction pair’s surface topography an important feature the running-in process. After directly affects performance in stable working state. contact pair was focused on by mostly existing studies after time; however, we should consider correlation before and running-in. In fact, exploration this problem significantly to extend service life parts improve running performance. Based...
Existing methods for modeling recommendation systems based on knowledge graphs include embedding-based, pathbased, and propagation-based methods. The embedding-based approach is flexible but more suitable intra-graph applications, the path-based can model complex relationships has a high computational cost, considers global information may introduce noise. This study proposed simple efficient model, called SEKGAT, which comprehensive ideology of propagation to personalized by aggregating...
