| 摘 要： | 含气页岩通常既可以作为烃源岩,又可以作为储层和盖层。页岩作为烃源岩,页岩气的产量与其总有机碳含量（TOC）、有机质的成熟度（Ro）、有效厚度密切相关;页岩作为储层,它有着低的孔隙度和渗透率,这也是它能作为盖层的原因。在页岩气藏中,气体主要是以吸附方式吸附在有机质和黏土颗粒的表面,或者以游离方式聚集在裂缝和孔隙中的。通过研究煤层气解吸机理,研究了页岩气的解吸机理及页岩中裂缝的检测方法。分析四川盆地烃源岩的地球化学特征、展布特征等,并探讨了四川盆地页岩气藏的分布。

| Abstract: | Gas-bearing shale is usually either as source rocks, but also can serve as reservoir and seal. As source rocks, its production is closely related to total organic content (TOC), thermal maturity (Ro) and total net thickness of shale sediments. As reservoir, shale possesses low porosity and permeability, so it can serve as seal. The gas in shale might be mainly stored as absorbed gas on kerogen and clay-particle surfaces, or free gas in natural fractures and intergranular pores. Based on the study of the coa... |
