随着当前能源消费的迅速增加,常规天然气资源短缺,很难满足日益增长的能源需求。页岩气作为一种非常规天然气,具有资源潜力大和低碳排放等优点,加之美国和加拿大成功实现商业化开采,因此页岩气资源勘探开发近年来备受世界瞩目。中国作为重要的页岩气开采国家,近几年发展势头良好,部分页岩气田也已经实现商业化生产。由于页岩的致密和低渗特性,导致页岩气的开采难度较大。页岩的孔隙结构和气体吸附扩散研究,对于气藏产能的评估及其高效开采有至关重要的作用。本文介绍了国内外页岩气勘探开发现状以及页岩的孔隙结构,综述了储层中页岩气吸附、扩散与渗流的研究进展,总结了分子模拟方法在页岩气研究中的应用,并对页岩气相关研究的前景进行了展望。
隨著噹前能源消費的迅速增加,常規天然氣資源短缺,很難滿足日益增長的能源需求。頁巖氣作為一種非常規天然氣,具有資源潛力大和低碳排放等優點,加之美國和加拿大成功實現商業化開採,因此頁巖氣資源勘探開髮近年來備受世界矚目。中國作為重要的頁巖氣開採國傢,近幾年髮展勢頭良好,部分頁巖氣田也已經實現商業化生產。由于頁巖的緻密和低滲特性,導緻頁巖氣的開採難度較大。頁巖的孔隙結構和氣體吸附擴散研究,對于氣藏產能的評估及其高效開採有至關重要的作用。本文介紹瞭國內外頁巖氣勘探開髮現狀以及頁巖的孔隙結構,綜述瞭儲層中頁巖氣吸附、擴散與滲流的研究進展,總結瞭分子模擬方法在頁巖氣研究中的應用,併對頁巖氣相關研究的前景進行瞭展望。

With the rapid increase of global energy consumption, the conventional natural gas resource is in shortage and difficult to meet the increasing demands. As a kind of unconventional gas, shale gas has a potential wealth of natural resources and the advantage of low carbon emission. With the commercial exploitation in America and Canada, shale gas has been drawing more and more attention. However, due to the tightness and low permeability of shale, shale gas is extremely difficult to produce. Therefore, understanding pore structure of shale as well as gas adsorption and diffusion is of great importance for the resource assessment and effective exploitation. In this review, domestic and overseas development progress of shale gas resource has been outlined, and the pore structures as well as the features of the shales are elaborated. The progress in molecular simulation of adsorption and diffusion of shale gas is summarized, and the perspective for shale gas is also provided.
