摘要:
为了探究水基SiO2纳米流体对煤体润湿性及瓦斯解吸特性的影响，采用低场核磁共振实验从微小孔隙层面分析水基SiO2纳米流体对煤样润湿性的影响，并通过搭建瓦斯吸附解吸实验平台，研究不同质量分数水基SiO2纳米流体对煤样瓦斯解吸的影响。研究结果表明：水基SiO2纳米流体能大幅缩短煤样渗吸平衡时间，渗吸平衡时质量分数为1.5%水基SiO2纳米流体润湿效果最优。水基SiO2纳米流体处理后的煤样瓦斯累计解吸量随水基SiO2纳米流体的质量分数升高而降低，煤的第1 min瓦斯解吸量（Q1）与水基SiO2纳米流体质量分数呈负相关。研究结果可为水基SiO2纳米流体在煤层注水中应用提供参考。
Abstract:
In order to investigate the influence of water-based SiO2 nanofluids on coal wettability and gas desorption characteristics,low-field nuclear magnetic resonance (NMR) experiments were conducted to evaluate the nanofluid-induced changes in coal wettability at the micropore scale.Additionally,a gas adsorption-desorption experimental setup was established to examine the effects of varying mass fractions of water-based SiO2 nanofluids on gas desorption behavior in coal samples.The results indicate that water-based SiO2 nanofluids significantly reduce the imbibition equilibrium time,with optimal wettability enhancement observed at a 1.5% mass fraction.Furthermore,the cumulative gas desorption from treated coal samples decreases as the nanofluid concentration increases.A negative correlation was found between the first-minute gas desorption quantity (Q1) and the mass fraction of water-based SiO2 nanofluids.The findings can serve as a valuable reference for the application of water-based SiO2 nanofluids in coal seam water injection.
