The efficient exploitation of marine oil and gas resources holds significant potential to mitigate the current severe energy crisis. Regrettably, incidents, such as kick even blowouts, can significantly impact normal development activities. displacement kill method is one effective strategy for well control in deep-water areas. In this study, detailed mathematical determining parameters involved operation by using was proposed. Of course, includes both cases: where fluid leaks during process...
Abstract The conceptual hydrogeological model of the low to medium temperature Daying and Qicun geothermal fields has been proposed, based on hydrochemical characteristics isotopic compositions. two are located in Xinzhou basin Shanxi, China exhibit similarities their broad‐scale flow patterns. Geothermal water is derived from regional groundwater system characterized by Cl·SO 4 ‐Na type. Thermal hydrochemically distinct cold having higher total dissolved solids (TDS) (>0·8 g/l) Sr...
This article presents a combined experimental and computational study to investigate the flow heat transfer in Y-fractal microchannel. Experimental apparatus was newly built effect of three different control factors, i.e., fluid rate, inlet temperature flux, on characteristics A standard k-Ɛ turbulence dynamics (CFD) model developed, validated further employed simulate comparison between simulated results obtained data presented discussed. Results showed that good agreement achieved current...
Intelligent mining risk assessment (MIRA) is a vital approach for enhancing safety and operational efficiency in mining. In this study, we introduce MIRA-ChatGLM, which leverages pre-trained large language models (LLMs) the domain of gas coal mines. We meticulously constructed dataset specifically designed analysis performed parameter-efficient fine-tuning on locally deployed GLM-4-9B-chat base model to develop MIRA-ChatGLM. By utilizing consumer-grade GPUs employing LoRA various levels...
土地利用/土地覆被变化(LUCC)与区域的可持续发展密切相关,分析土地利用变化及其空间变量的关系,建立模拟模型来认识和揭示土地利用变化的特征和时空分布规律,为未来规划和政策的制定提供支持是LUCC研究的重点问题之一.本研究以太湖流域上游典型丘陵山区茶园开发作为重点研究对象,结合中高分辨率遥感影像信息、1:50000国家标准地形图数据和野外土壤采集分析数据获取2000年以来茶园及其它土地利用信息、研究区地形地貌数据和土壤数据,通过对2000年以来茶园及其新开茶园的区位分布分析,发现茶园的变化呈现快速增长的趋势,11年研究区茶园面积扩大了5倍,其中一半以上的面积是最后3年增长的;茶园在流域上不同分区的分布差异比较大,这些差异与分区自然条件、区位条件和开发条件有一定关系.根据Cramer...
The mechanical properties of coal containing fluid are an important factor affecting the safe mining soft seams. In particular, for class III-V coal, and gas outbursts other dynamic phenomena prone to occur due influences pressure groundwater, which seriously threaten safety lives field workers. However, briquette samples usually used in place raw laboratory tests conducted on samples. Whether research conclusions consistent whether can replace strength characteristics need be further...
Vacuum dewatering is a highly energy-intensive process that widely adopted in industrial production such as papermaking and chemical manufacture. A significant portion of the energy consumed by vacuum system converted into drives airflow passing through wet fiber web. During conversion process, part wasted due to redundant capacity pump, which caused deviation rate estimation during design system. To improve rate, variable porosity model (VPM) proposed this study better simulate porous...
Bearingless motor, which combines characteristics of alternating current motor and magnetic bearing, can operate without magnetism suspension bearing by making use winding that produce suspending power in the stator. Through torque decoupling control, it make rotor to simultaneously. The bearingless features high speed little friction etc. It is one hot research areas. design control system key this research. basic principle introduced based on directional field provided paper.
