The approach combines Mogi–Coulomb criterion using intermediate stress for wellbore shear failure. It considers rock shear breakdown in fracture pressure calculations and predicts reservoir shear slip with Jaeger criterion and drilling fluid invasion on the weak surface in calculating wellbore tensile failure. The study finds that instability in the well wall of this block is not solely due to the intermediate stress criterion or shear fracture of intact rock. Instead, during drilling with high-density fluid, the weak surface (fracture) undergoes shear-slip damage before intact rock. The collapse is a result of the interplay between bit replacement, dynamic drilling loads, and drilling fluid intrusion, causing tensile rupture on the weak surface and repeated fluid leakage. Analysis of wellbore instability in 16 wells within ultra-deep complex formations shows that the collapse pressure prediction accuracy is 87.5%, and the loss pressure prediction accuracy is 93.7%. Compared to traditional methods, this approach is more accurate and practical, providing essential guidance for resolving wellbore instability issues in drilling operations.

This study gave an in-depth insight on the imbibition characteristics during the soaking stage under non-zero initial water saturation conditions by static soaking and dynamic waterflooding of the core. The results indicate that the fluid absorbed by SI in the core is short-ranged. After SI, there is still a substantial amount of remain oil (30.7%) that can be displaced by subsequent FDI. SI considerably drives oil recovery in small pores (10–100 nm), whereas FDI is more effective in large pores (500–1000 nm). Controlling the rate of fracturing water flowing into the matrix from the fracture can enhance the combined effect of SI and FDI.

One of the common problems encountered in wave-shaped foam drainage pipelines is the inaccurate prediction of the liquid retention rate. This issue makes it difficult to predict liquid accumulation points, which affects gas output efficiency, causes pipeline corrosion, and generates natural gas hydrates. To clarify the liquid-holding rate law of wavy foam drainage pipelines is studied. In this study, through experiments to verify the accuracy of the numerical simulation method, we investigate the easiest liquid accumulation points and the liquid-holding rate of wave-shaped foam drainage pipelines, with factors such as inlet gas velocity, inlet liquid velocity, import and export differential pressure, undulation angle, and inlet temperature change rule. Among them, the error between the numerical simulation results and the experimental results is 4.68%. Finally, after considering the influence of the aforementioned factors on the liquid retention rate of wave-shaped pipelines, a new liquid retention rate calculation model for wave-shaped pipelines with foam drainage is established by introducing dimensionless numbers, such as gas-phase velocity coefficient, liquid-phase velocity coefficient, and angle correction coefficient. The method is compared with the results of previous research, and the error is within 15%.

The main objective is to minimize the total cost, achieved by minimizing the cost of the new cables connecting the depot station to the distribution system and the upgrade cost of existing lines to meet the additional loads. The outcomes are the optimal location of the depot, the optimal electric node bus in the distribution system to supply it, and the required system upgrades. The optimization problem is formulated as a Mixed Integer Nonlinear Programming (MINLP) model and solved using the General Algebraic Modeling System (GAMS). The methodology is tested on the H16 EB service line in Barcelona, Spain, and a typical electrical distribution system. Three case studies are presented in this paper. In the first case, the impact of a single service on the distribution network is analyzed, and in the second case, three H16 EB services are assumed to serve the network. The third case handles a multi-route, multi-terminal bus service to allocate and supply a depot capable of accommodating all the routes. This case will also include sensitivity analysis to test the robustness and reliability of the model. Results show that for a single H16 EB service, no line upgrades were needed, and the total cost per phase was $120,000. For three H16 EB services, three lines required upgrades, and the total cost per phase increased to $718,000. In the third case, the sensitivity analysis revealed that higher demand factors lead to increased costs due to more update requirements and voltage deviations. The results demonstrate that the minimum distance between the depot and node is not always the optimal or feasible solution that would prevent the depot load installation at a weak spot and meet the power flow constraints.</p>","PeriodicalId":11673,"journal":{"name":"Energy Science & Engineering","volume":"12 12","pages":"5466-5479"},"PeriodicalIF":3.5,"publicationDate":"2024-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ese3.1955","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142868609","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Energy consumption has been an ongoing concern in the railway sector practically since its inception. There has always been an interest in finding solutions to reduce it, such as improvements in rolling stock design and the use of regenerative braking which will not be analyzed in this article, and optimal train movement, operation and timetabling, and infrastructure design.

While some research has addressed the relationship between population aging and energy consumption or generalized carbon emissions, its impact on living carbon emissions has been less explored. This study uses provincial panel data from the Yellow River Basin (2006–2020) and employs a threshold regression model to analyze the relationship between population aging and living carbon emissions. A Multiple Mediation Effect Model is also applied to explore the mechanisms behind this relationship, with a comparative analysis between urban and rural areas. The results indicate a U-shaped nonlinear effect of population aging on living carbon emissions, which are initially inhibited and then promoted, with different “turning points” for rural and urban regions. As income levels rise, population aging has a marginally increasing effect on living carbon emissions. However, upgrading the consumption expenditure structure, expanding family size, and increasing clean energy consumption can help mitigate the promoting effect of aging on emissions. The mediation model identifies four pathways through which population aging influences living carbon emissions, with income level and consumption expenditure structure playing key roles.

Engineering practice shows that drilling pressure relief has obvious time-effect. Through the establishment of drilling pressure relief numerical model, the evolution law of stress field and plastic zone in different periods after drilling was studied. The evolution of the pressure relief effect of large-diameter borehole is closely related to the development degree of cracks around the borehole. The stress transfer process after drilling can be divided into the pressure relief beginning stage, rapid pressure relief stage, and pressure stable stage. The pressure relief time effect is affected by borehole parameters. When the diameter increases from 100 to 250 mm, the time required for the stress transfer process is reduced by 50%. When the borehole spacing is reduced from 2 to 0.5 m, the time required for the stress transfer process is reduced by 33.3%. Changing the borehole depth has no significant effect on the stress transfer rate.
