The seepage erosion of underground defective pipelines can negatively affect the structure and stability surrounding strata, leading to severe urban ground collapses. Revealing failure mechanism mechanical characteristic is crucial for their prevention mitigation. A large-scale physical modeling experiment was carried out a coupled Computational Fluid Dynamics-Discrete Element Method (CFD-DEM) numerical model proposed. microscopic soil–water interactions during process were researched,...
Summary Driven by groundwater, defective pipelines can cause soil erosion and pose significant risks to the surrounding infrastructure. In this study, evolution collapse characteristics of formation stress caused were considered not only under constant groundwater level condition that previous studies have focused on but also rainfall or flood scenarios (the rises briefly then quickly returns its original height). This study developed a large-scale 3×2×2 m 3D physical model experimental...
Abstract Geothermal energy has been widely proposed as a potential renewable to replace traditional fossil fuel energy. Hot dry rock (HDR) reservoirs were the main geothermal resources and usually consist of low‐permeability hard granite without fluid. Developing HDR requires water cyclically flowing between injection production wells extract heat Hydraulic fracturing, key reservoir stimulation technology, can create path fluid flowing. However, few studies have investigated hydraulic...
Abstract The microseism induced by hydraulic fracturing is of great significance to the development geothermal reservoirs and site selection systems. In this study, taking field data from Qiabuqia as a geological reference, several models are developed for simulations based on included in commercial FracMan™ software suit. A series numerical carried out explore effects different fracture parameters, including existence faults, in-situ stress state, occurrence, distribution near microseisms....
Abstract Reservoir temperature estimation is crucial for geothermal studies, but traditional methods are complex and uncertain. To address this, we collected 83 sets of water chemistry reservoir data applied four machine learning algorithms. These models considered various input factors underwent preprocessing steps like null value imputation, normalization, Pearson coefficient calculation. Cross-validation addressed volume issues, performance metrics were used model evaluation. The results...
As an attractive renewable energy source, deep geothermal is increasingly explored. Granite a typical reservoir rock type with low permeability, and hydraulic fracturing promising stimulation method which could obviously enhance the permeability. Previous studies were mostly conducted on artificial samples small cylindrical granites. The pressures of real sample much lower than that field operation, it was difficult to observe morphological changes in rocks. Hence, this paper presents...
Currently, water fracturing under deep geothermal conditions remains poorly understood because the reservoir rocks are usually high-strength crystalline characterized by high temperatures. The aim of this study is to investigate effects rock properties, injection rates, and temperatures on hydraulic behavior induced crack characteristics through experimental investigations. A series experiments was conducted two Indosinian granite types differences in caused properties. Among others, six...
The purpose of the study was to investigate and analyse inner strength patients with peritoneal dialysis, explore associations among strength, coping self-efficacy (CSE) medial modes.
In the Enhanced Geothermal System (EGS), flow state of fracture thermal reservoir (granite) is important for heat transfer. this paper, effects temperature, rate and shape on convection that occurs in rough granite are studied based fractal dimension theory. The manufactured regularly by carving technology. shear experiments were carried out at confining pressures 10, 15 20 MPa to analyze state. convective transfer conducted 60 70 °C simulate different conditions. results indicated outlet...
High-frequency impacting and rolling was applied on AZ31B magnesium alloy to obtain a gradient nano-structured surface. Surface characteristics were experimentally investigated, the nanocrystallization mechanism is discussed in detail. Results showed that nano-structure with of work hardening, compressive residual stress smooth surface induced treated Grains top generally refined around 20 nm. Twins, dislocations dynamic recrystallization dominated grain refinement process. Fatigue strength...
This study investigates the influence of temperature, effective stress, and rock fracture on bulk modulus Biot’s coefficient granodiorite from a hot dry geothermal reservoir using triaxial compression test. Three types representative samples were chosen for comparative experiments. The experiments conducted with 0–55 MPa stress under cyclic loading. Results show that can continuously increase in at constant temperature. influencing law is opposite modulus. Interestingly, temperature effects...
Aim This study aims to assess the extent of social alienation in patients undergoing peritoneal dialysis and examine how personal mastery perceived support mediate association between emotional intelligence this patient population. Methods adopts a cross-sectional survey design. A total 192 were recruited from tertiary hospital located Henan Province, China, using convenience sampling method. We have developed structural equation model investigate mediating influence on Peritoneal dialysis....
