正确认识产气页岩孔隙是开发页岩气资源的基础,为此,运用氩离子抛光—扫描电镜和高压压汞技术对四川盆地威远地区筇竹寺组产气页岩的孔隙类型及微观结构特征进行研究。将研究区层段页岩孔隙分为5大类(包括粒间孔、粒内孔、晶间孔、微... 正确认识产气页岩孔隙是开发页岩气资源的基础,为此,运用氩离子抛光—扫描电镜和高压压汞技术对四川盆地威远地区筇竹寺组产气页岩的孔隙类型及微观结构特征进行研究。将研究区层段页岩孔隙分为5大类(包括粒间孔、粒内孔、晶间孔、微裂缝和有机质孔隙)。高压压汞实验结果显示,产气页岩孔径分布复杂,2-50 nm的中孔最为发育,含有少量大孔。页岩排驱压力较高,孔隙存在明显的细颈瓶特征,孔喉分选性、连通性较差,退汞效率低,中孔对气体的渗流和储集起明显作用。 展开更多

It has been commercially developed in North America and other places. Featuring a vast distribution, a low abundance,unfavorable reservoir conditions, ultra-low permeability and a fast production decline, shale gas is more difficult to develop than conventional natural gas, as it needs advanced drilling and completion technology to develop. During the early stage of shale gas exploration and development, the United States offered enterprises necessary incentives such as tax reductions and exemptions and subsidies to achieve sustainable shale gas development and encourage technological progresses. By comparing the state of China's shale gas development with that of the US' in terms of geological conditions, production technology,market price, tax relief, subsidy periods and amount, this paper intends to put forward related suggestions for the effective development of shale gas according to the current status of development. 展开更多

Ever since 2005, the US' shale oil and gas production growth and effective adjustment of domestic energy consumption mix have made it possible for the country to be less dependent upon imported energy and gain energy independence. What should we learn from it to guarantee energy supply security? This paper tried to answer the question. 展开更多
