Abstract: Geological anomalies in underground coal seams pose serious risks to mining safety and productivity. This study applies an integrated geophysical approach—combining radio wave imaging and channel wave seismic methods—to investigate the structural integrity of the 31123-1 working face at Dongxia Coal Mine, China. Radio wave results indicated stable field intensities and low absorption coefficients, suggesting overall seam continuity with minor localized anomalies. Subsequent channel wave surveys confirmed the absence of faults or collapse features and identified a broad synclinal structure as the only significant anomaly. The findings demonstrate that integrating electromagnetic and seismic techniques enhances structural resolution and provides a reliable basis for safe and efficient mine planning in complex geological settings.

Abstract: [Objective]Aiming at the complex gas-water relationship faced in the development of the Sulige Gas Field, this study explores the main controlling factors of gas-water distribution in its tight gas reservoirs to provide a theoretical basis for the efficient development of the gas field[1]. [Methods]By analyzing the hydrochemical characteristics of formation water, classifying the types of produced water, and combining parameters such as the chlorosodium coefficient and metamorphism coefficient, the planar distribution characteristics of gas and water were studied. The influencing factors of gas-water distribution were analyzed from aspects including hydrocarbon generation intensity, reservoir physical properties, microstructures, and tectonic features. [Results]The formation water is dominated by CaCl₂type with high salinity (25–32 g/L)[2], which can be divided into three categories: formation water, condensate water, and residual flowback fluid. The gas-water distribution shows spatial heterogeneity: water layers are widely developed in the lower part of He 8 Member, while water layers in Shan 1 Member appear as isolated lens bodies. In areas where the hydrocarbon generation intensity is lower than 20×10⁸ m³/km², water layers account for 65%; the gas displacement efficiency of high-quality reservoirs (porosity >9.32%, permeability >0.67 mD) exceeds 75%[3]; gas enrichment occurs in the overlapping areas of the west-dipping monocline structural high and delta distributary channel sand bodies. [Conclusions]Hydrocarbon generation intensity dominates the macro-differentiation of gas and water, reservoir physical properties determine the micro-occurrence, and tectonic features regulate the gas-water distribution pattern. This study provides a geological basis for the "avoiding water and seeking gas" development strategy of the gas field. Read More

Abstract: More than two decades after the development of Block D, it has entered the later stage of reservoir steam uptake development, and the difficulty of oil and gas exploration is increasing. To enhance the recovery rate of the block, countermeasures were studied in response to the current contradictions of poor steam injection effect, low formation energy, increased steam flow, uneven longitudinal utilization, and a large number of casing loss Wells. Planning and deployment were carried out to optimize steam injection parameters, implement carbon dioxide uptake, complement profile control technology measures, implement stratified steam injection and increase the intensity of major overhauls. In the field application process, the production effect was effectively improved. To propose development directions for high-cycle ultra-heavy oil blocks. Read More

Abstract: With the expansion of oil and gas resource development to complex terrain areas, the problem of gas-liquid two-phase flow in long-distance pipeline transportation of wet natural gas has become a core concern in the industry. This article systematically reviews the research progress on the flow characteristics, critical liquid carrying velocity, pressure drop, and holdup prediction models of gas-liquid two-phase flow in response to the decrease in transportation efficiency and safety risks caused by liquid accumulation in low-lying areas of wet natural gas pipelines. Research has shown that existing achievements have preliminarily revealed the dynamic mechanism of fluid accumulation and airflow carrying, but there is still a lack of systematic research on the non-uniformity of flow in complex terrains, the universality of models for high-pressure conditions with large pipe diameters, and droplet entrainment effects. Domestic and foreign experimental and theoretical models (such as laminar flow model and ARS interface model) provide a basis for parameter prediction, but the limitations of experimental conditions and the closure problem of interface parameters restrict engineering applications. Future research needs to integrate fractal theory, high-speed measurement technology, and deep learning algorithms to construct a cross scale gas-liquid interface dynamic model, strengthen the coupling mechanism of multiple physical processes, and verify actual pipeline data to improve the accuracy of pipeline design and operation optimization. This review provides direction references for theoretical breakthroughs and technological innovations in the safe and efficient transportation of wet natural gas pipelines Read More

Abstract: The carbon emission of industrial energy consumption has an important impact on a region's carbon emission reduction and optimization of carbon emission path. Based on the STIRPAT model and the TAPIO decoupling model, this study analyzes the driving factors and decoupling relationship between carbon emissions from industrial energy consumption and economic growth in Sichuan Province. The research shows that: (1) The industrial carbon emissions in Sichuan Province are increasing first and then decreasing, with an increase of 18.78% from 2005 to 2022, and the carbon emission intensity has decreased from 1.94 tons/10,000 yuan to 0.29 tons/10,000 yuan; (2) The decoupling relationship between industrial carbon emissions and economic growth in Sichuan Province presents three development periods, mainly strong decoupling and weak decoupling. According to the decomposition factors, the decoupling relationship between industrial carbon emissions and economic development is mainly affected by the decoupling coefficient of value creation and emission reduction; (3) The proportion of secondary industry, the number of industrial enterprises, and the total industrial assets are the main carbon promoting factors of industrial carbon emission in Sichuan Province, with elastic coefficients of 0.097, 0.057 and 0.040 respectively; population size is a carbon reduction factor with an elastic coefficient of -0.087. Finally, the study puts forward some suggestions to realize industrial carbon emission reduction. Read More

Abstract: Water-rock interactions play a critical role in shaping the geochemical and geomechanical characteristics of subsurface formations in oil-rich regions. Resource extraction in oil-rich regions significantly disrupts hydrogeological systems, particularly through water-rock interactions that affect long-term regional sustainability. The research adopts an economic perspective to assess the impact of oil extraction on subsurface geochemistry, focusing on the economic valuation of water degradation due to mineral dissolution, salinity shifts, and mobilization of trace elements. The operation is carried out using IBM SPSS software version 27.0, where multivariate regression analysis and t-tests are used to statistically model the relationship between extraction intensity, groundwater chemistry, and socio-economic outcomes across major oil-producing regions. The analysis incorporates time-series data on water quality indices, oil output, and regional economic indicators such as agricultural productivity loss, healthcare costs, and water treatment expenditures. Findings show a statistically significant correlation (p < 0.01) between increased extraction rates and elevated concentrations of sodium, chloride, and heavy metals in local aquifers. In high extraction zones, the average agricultural productivity is 2.34 tons/ha, while in low extraction zones it is 2.91 tons/ha (t = -4.73, df = 98, p < 0.001). Public health expenditure in high extraction areas averaged $124.7 USD/capita, compared to $89.3 USD/capita in low extraction areas (t = 5.16, df = 98, p < 0.001). The research defines regional sustainability as the balance between environmental protection, economic resilience, and social well-being in oil-rich areas, assessing groundwater degradation, economic losses, and community impact caused by water-rock interactions linked to oil extraction activities.
