| 摘 要： | 页岩气在复杂孔渗空间的流动属典型的多尺度多场耦合流动。开展页岩气渗流机理研究，有助于揭示页岩气藏中流体运移机制，为后期建立数学模型、开展数值模拟研究及产能评价与预测奠定理论基础。在调研国内外相关文献的基础上，并结合近期已开展的工作，从页岩孔隙结构特征、吸附解吸规律、含气量测试、应力敏感性、储层流体运移等实验内容以及分子动力学方法、直接蒙特卡洛方法和格子Boltzmann方法等微观流动机理模拟方法两方面进行归纳总结，阐述了页岩气渗流机理的研究进展，指出气体吸附程度对渗流规律的影响研究、页岩气多尺度介质流动机理实验评价装置研制、页岩气藏气水两相流动实验与理论研究是未来的发展方向。

| Abstract: | The flow of shale gas in complex porous space is a typical case of multi-scale and multi-field coupled flow. Studying shale gas seepage mechanisms helps to reveal the mechanism for fluid migration in shale gas reservoirs, and lays a theoretical foundation for the establishment of a mathematical model, development of numerical simulations, and evaluation and prediction of future yields. Based on a literature review from China and abroad combined with recent work, we summarized current research in the field from two perspectives:1) experimentally, in terms of pore structure characteristics of shale, adsorption desorption patterns, shale gas content tests, stress sensitivity, and reservoir fluid migration and 2) theoretically, in terms of micro-flow mechanism simulations, such as molecular dynamics, direct simulation Monte Carlo, and lattice Boltzmann. The progress in the research on shale gas seepage mechanism are also described. The following areas are envisioned as the future direction of research:the influence of gas adsorption on the percolation pattern, fabrication of experimental devices to evaluate shale gas multi-scale media flow mechanisms, and experimental and theoretical studies of shale gas reservoir gas-water two-phase flow. |
