摘要

在煤层气热采中，红外辐射技术可以提高岩石渗透率，促进甲烷解吸。本文建立了红外辐射实验系统，研究了不同含水量下煤的吸附/解吸行为。结果表明，红外辐射功率越大，煤的吸附能力越低，解吸能力越强。具体来说，采用50 W的红外辐射可使解吸能力增加30.9%。较高的含水率加剧了解吸滞后效应，而红外辐射可以通过更高的功率水平来减轻这种不利影响，表现出更强的降低解吸滞后的能力。此外，还建立了红外辐射的临界压力。在此压力前后，红外辐射功率对压力灵敏度的影响有明显差异。最后，提出了一种考虑红外辐射功率和含水率的改进Langmuir吸附模型，并用实验数据进行了验证。本研究拓展了红外辐射技术在实际开采中提高煤层气采收率的应用。文献类型:原文引用号:涂颖，张颖，董颖，马颖。红外辐射下煤层气吸附与解吸特性研究。毛细管学，2023,8(3):53-64。https://doi.org/10.46690/capi.2023.09.02

Adsorption and desorption characteristics of coal seam gas under infrared radiation

Infrared radiation technology can enhance rock permeability and promote methane desorption in coalbed methane thermal recovery. In this study, an experimental system with infrared radiation is developed to investigate the adsorption/desorption behavior of coal under different water contents. The results demonstrate that higher power levels of infrared radiation lead to decreased adsorption capacity and increased desorption capacity in coal. Specifically, employing 50 W infrared radiation results in a 30.9% increase in desorption capacity. Higher moisture content intensifies the desorption hysteresis effect, while this adverse impact can be mitigated by infrared radiation with greater power levels, exhibiting a stronger ability to reduce desorption-induced hysteresis. Additionally, a critical pressure for infrared radiation is established. Before and after this pressure, the influence of infrared radiation power on pressure sensitivity differs significantly. Finally, an improved Langmuir adsorption model considering infrared radiation power and moisture content is proposed and validated using experimental data. Our research expands the application of infrared radiation technology for enhanced coalbed methane recovery during actual mining operations.
