中国页岩气资源前景与战略地位

Prospects and strategic position of shale gas resources in China

随着页岩气开采技术进步和勘探投入条件的改善,页岩气的开采活动将进一步繁荣和快速扩展。在介绍国内外页岩气资源量的基础上,分析了中国页岩气资源勘探开发前景以及页岩气资源的战略地位。研究表明:从我国油气总体发展的战略角度,积极寻找天然气后备资源已是当务之急;我国地质历史时期广泛发育的富含有机质的页岩地层具有优越的页岩气形成与富集条件,资源潜力巨大,勘探开发前景广阔,必将成为新的天然气勘探开发重要领域。建议加大页岩气资源的研究力度和勘探投入,形成我国的页岩气资源储备和勘探开发特色技术;我国南方的古生界下组合泥页岩、北方中生界泥页岩等层系具有较好的页岩气勘探前景,建议通过老井复查优选有利井段进行试气和试采,以点带面,开创页岩气勘探开发新局面。

Production of shale gas will get more prosperous and will expand rapidly along with technical progress and improvement of economic conditions.The prospects of shale gas exploration and production and the strategic position of shale gas resources in China are analyzed after introducing the domestic and foreign shale gas resource volumes.As required by the overall development strategy of petroleum industry in China,prospecting for natural gas reserves is a task of top priority.The organic-rich shale formations were extensively deposited in different geologic periods in China and had favorable conditions for the generation and accumulation of shale gas.They have huge potentials of gas resources and bright prospects of exploration and production,and will surely become a major new field of gas exploration and production.It is proposed to strengthen research and increase exploration investment in shale gas.The shale and mudstone in the lower sequences in South China and those in the Mesozoic in North China have relatively large potential for shale gas exploration.It is proposed to perform gas testing or production test in the favorable intervals selected through reviewing old wells,so as to open a new stage of shale gas exploration through fanning out from point to area.
