This paper reviews the recent research progress of MSI on Ni-based catalysts and their characterization and modulation strategies in catalytic reactions. From the perspective of MSI, the effects of different carriers (metal oxides, carbon materials and molecular sieves, etc.) are introduced on the dispersion and surface structure of Ni active metal particles, and the effect of MSI on the activity and stability of DRM reactions on Ni-based catalysts is discussed in detail.

First, the Dengying gas reservoirs on both sides of the rift trough are predominantly composed of oil-cracking gas with high maturity, which is typical dry gas. Second, severely modified by thermochemical sulfate reduction (TSR) reaction, the Dengying gas reservoirs on the east side exhibit high H₂S and CO₂ contents, with an elevated δ¹³C₂ value (average value higher than −29‰). The Dengying gas reservoirs in the Weiyuan area are less affected by TSR modification, though the δ¹³C₁ values are slightly greater than that of the reservoirs on the east side with partial reversal of carbon isotope composition, likely due to the water-soluble gas precipitation and accumulation mechanism. The Dengying gas reservoir of Well Datan-1 shows no influence from TSR. Third, the Dengying gas reservoirs reflect high helium contents (significantly higher than that on the east side) in the Weiyuan and Datan-1 areas on the west side, which is supposed to attribute to the widespread granites in basement and efficient vertical transport along faults. Fourth, controlled by the paleo-salinity of water medium in the depositional period of the source rock, the δ²H_CH4 values of the Dengying gas reservoirs on the west side are slightly lighter than those on the east side. Fifth, the Dengying natural gas in the Datan-1 area is contributed by the source rocks of the Sinian Doushantuo Formation and the third member of the Dengying Formation, in addition to the Cambrian Qiongzhusi Formation.</div></div>","PeriodicalId":67426,"journal":{"name":"Petroleum Exploration and Development","volume":"52 2","pages":"Pages 422-434"},"PeriodicalIF":7.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143873786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among such, blast waves impacting the platform's structure represent critical conditions that have not yet been studied in detail. That is, frameworks for vulnerability assessment that can deal with blast loading have not been presented yet. In this context, this work presents a fast-running engineering tool that can quantify the risk that a structure fails when it is subjected to blast loading from the detonation of high explosive-driven threats detonating at various distances from the structure itself. The tool has been implemented in an in-house software that calculates vulnerability to various impacting objects, and its capabilities have been shown through a simplified, yet realistic, case study. The novelty of this research lies in the development of an integrated computational environment capable of calculating the platform's vulnerability to blast waves, without the need for running expensive finite element simulations.

Traditionally, during rotary friction welding, the severely deformed material, or flash, is expelled from the interface and machined away to achieve the desired joint geometry. However, this work introduces a novel approach: trapping the flash within the joint to improve joint properties. The study investigates two different interface geometry combinations—flat-flat and flat-taper interfaces. Previous research shows that Ni interlayer between steel and titanium can enhance the joint strength. This study builds on the existing knowledge (effect of Ni interlayer) by examining the influence of interface geometry to further improve the dissimilar joint performance. The experimental results, including tensile testing and microstructural characterization, highlight the superior performance of the flat-taper interface. The modified geometry minimizes flash loss, providing a cavity that retains both the flash and the Ni interlayer within the joint. This retention promotes dynamic recrystallization, resulting in refined grain structures near the interface. Moreover, the trapped Ni interlayer effectively prevents the formation of brittle Fe-Ti intermetallic compounds at the dissimilar material interface. The findings reveal that the flat-taper interface improved joint strength by an impressive 105% compared to the flat-flat interface. This innovative geometry modification demonstrates the potential to enhance mechanical properties of dissimilar joints through better flash and interlayer management.</div></div>","PeriodicalId":58209,"journal":{"name":"Defence Technology(防务技术)","volume":"46 ","pages":"Pages 71-78"},"PeriodicalIF":5.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143829989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A brand-new volume boundary element numerical method solution has been developed and verified and tested. The influences of internal flow and flow boundary of the reservoir on strata deformation are equivalent to the impacts on strata deformation when external forces act at the interior and boundary of the reservoir, respectively. Calculation methods for the flow equivalent force and boundary equivalent force are provided. The deformation solution at any point in the strata can be obtained through the convolution of flow equivalent forces, boundary equivalent forces and Green's functions. After discretization, the deformation solution at any point in the strata can be obtained by multiplying the grid boundary equivalent forces, grid flow equivalent forces with their corresponding grid boundary sources and grid volume sources respectively, and then summing them up. This numerical method is termed the Volumetric Boundary Element Method (VBEM). Compared with traditional commercial simulators, VBEM fully considers the effects of reservoir flow boundaries, pore pressure gradient fields within the reservoir, and fluid mass changes within pores on formation deformation. It eliminates the need for meshing outside the reservoir, achieves significantly improved solution accuracy, and provides a new technical framework for simulating deformation induced by reservoir development.</div></div>","PeriodicalId":67426,"journal":{"name":"Petroleum Exploration and Development","volume":"52 2","pages":"Pages 485-495"},"PeriodicalIF":7.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143873248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work developed a new interpretable machine learning (ML) framework to specifically address this issue. Three different methods, namely random forest (RF), support vector regression (SVR), and artificial neural network (ANN), were used to establish proxy models using the data from a specific unconventional reservoir, and the RF model demonstrated a preferable performance. To enhance the interpretability of the established models, the multiway feature importance analysis and Shapley Additive Explanations (SHAP) were proposed to quantify the contribution of individual features to the model output. Based on the results of model interpretability, the genetic algorithm (GA) was coupled with RF (RF-GA model) to optimize the CO₂-EOR process. The proposed framework was validated by comparing the GA-RF predictions with simulation results under different reservoir conditions, which yielded a minimum relative error of 0.34% and an average relative error of 5.3%.
