To enhance ultimate recovery of hydrocarbon gases from unconventional gas resources such as shales, we need to uncover the non-intuitive gas transport mechanisms in ultra-tight porous media. Exploiting our previous and recent pioneering work in modelling rarefied gas flows at micro/nano-scales and in pore-scale characterisation of reservoir rocks, we present an ambitious project to tackle this newly-emerged research challenge through developing direct numerical simulation models and techniques that work on binarised images of concerned porous materials. This work will transform the currently-adopted heuristic approaches, i.e. Darcy-like laws and pore network modelling, into those underpinned by the first principle, and enable the quantification of prediction uncertainty on gas transport associated with the former approaches. Timely support now from EPSRC will provide us crucial resources to shape this emerging research area - understanding and quantifying gas flow physics in ultra-tight porous media.

为了提高页岩等非常规天然气资源中烃类气体的最终采收率，我们需要揭示超致密多孔介质中非直观的气体运移机理。利用我们以前和最近的开创性工作，在微观/纳米尺度上模拟稀薄气体流动和储层岩石的孔隙尺度表征，我们提出了一个雄心勃勃的项目，通过开发直接的数值模拟模型和技术来解决这一新出现的研究挑战，这些模型和技术适用于有关多孔材料的二值化图像。这项工作将目前采用的启发式方法，即达西定律和孔隙网络建模，转化为第一原理的基础上，并使与前方法相关的气体输运的预测不确定性的量化。EPSRC的及时支持将为我们提供关键资源，以塑造这一新兴的研究领域-理解和量化超致密多孔介质中的气体流动物理。
