日前本刊记者从中国地质调查局获悉,我国页岩气资源潜力巨大,发育层系多。目前已在四川盆地及周缘下古生界海相龙马溪组和牛蹄塘组获得页岩气勘查开发重大突破,并形成产能,有望实现《页岩气发展规划(2011~2015)》提出的65亿立方米产量的目标。在四川盆地及周缘中生界陆相、鄂尔多斯盆地三叠系陆相、西北侏罗系陆相和华北石炭—二叠系海陆交互相等领域获得页岩气调查重要发现。初步形成了海相页岩气“二元”富集和成藏模式,以及适合我国地质条件的页岩气勘查开发技术体系,装备基本实现国产化,页岩气勘查开发基本实现绿色环保。
Recently, our correspondents learned from the China Geological Survey that shale gas resources in China have great potential and many developmental strata. At present, significant breakthroughs in shale gas exploration and development and production capacity have been obtained in the Paleozoic marine Longmaxi and Niutitang formations in the lower margin of the Sichuan Basin and the margin, and the “shale gas development plan (2011 ~ 2015)” 65 Billion cubic meters of output target. Important findings of shale gas surveys have been obtained in the continental basins of the Sichuan Basin and its peripheries, the Triassic continental facies of the Mesozoic, Ordos Basin, the continental facies of the northwestern Jurassic and the North China Carboniferous-Permian intercontinental. The marine shale gas “duality” enrichment and accumulation model and the shale gas exploration and development technology system suitable for China’s geological conditions have been initially formed. The localization of equipment is basically achieved and the shale gas exploration and development basically achieves green environmental protection .
