摘要: 介绍了中国页岩气的资源潜力,分析了中国页岩的地史和空间分布,对比了中国三大类富有机质页岩的特征及中国页岩气与北美的差异。我国页岩气地质资源量介于80.45×1012 ~144.50×1012,可采资源量介于11.50×1012~36.10×1012。在中国多旋回构造与多沉积环境演化的过程中形成了从中元古界串岭沟组到渐新统东营组的多套复杂的页岩沉积。其中,海相页岩主要形成于早古生代时期,主要分布在中下扬子区、四川盆地及周边为主的南方地区和塔里木盆地为主的中西部地区,资源潜力最大,成藏条件优越,层系上以筇竹寺组和五峰组—龙马溪组及其相当层位为重点;海陆交互页岩主要发育于晚古生代,以准噶尔盆地、鄂尔多斯盆地、塔里木盆地等中西部沉积盆地的石炭系—二叠系和南方地区的二叠系,以太原组、山西组、龙潭组为重点层系,资源潜力和成藏条件次于海相页岩;陆相页岩则形成中、新生代,分布于鄂尔多斯盆地、渤海湾盆地、松辽盆地、四川盆地等沉积盆地,以延长组、青山口组、沙河街组和三叠系-侏罗系为重点层系,资源潜力和成藏条件最差。

Abstract: This paper introduces the resource potential,analyzes the geological history and space distribution of shale gas in China.Then it compares the characteristics of three main types of organic-rich shale in China and studies the difference of shale between China and North America. The geological resource quantity of shale gas in China is between 80.45×1012~144.50×1012,among which the recoverable resource is between 11.50×1012~36.10×1012. Many complicated shale formations were deposited from Chuanlinggou Formation in Mesoproterozoic Erathem to Dongying Formation in Oligocene in the process of polycycle tectonic and sedimentary environment evolution in China. Marine shale,formed at early paleozoicera,is superior in resource potential and reservoir forming conditions,mainly distributed in south China's middle-lower part of Yangtze region,Sichuan Basin and central and western China's Tarim Basin,with most important stratas of Qiong-zhu-si Formation,Wu-feng&Long-ma-xi Formations.Inferiorto Marine shale,the transitional shale,developed at late paleozoicera is distributed in Carboniferous-Permian of Sedimentary basin in the mid-western China's Jung-gar Basin,Ordos Basin,Tarim Basin and Permian in South China,with importants tratas of Taiyuan,Shanxi and,Long-tanFormations.While,next to the transitionalshale,the continental shale,formedat Mesozoic and Cenozoicera,is distributed in Song-liao,Bo-haiBay,OrdosandSichuan basins,with important stratas of Yan-chang,Qingshan-kou,Sha-he-jie Formations,Triassic and Jurassic systems.
