在当前国际能源供需矛盾日益突出的形势下,页岩气资源勘探开发备受世界瞩目。从全世界范围看,泥、页岩约占全部沉积岩的60%,页岩气资源前景巨大。全球页岩气资源量为456.24×1012m3。主要分布在北美、中亚和中国、拉美、中东和北非、前苏联(如表1)。 In the current situation of increasingly prominent contradiction between international energy supply and demand, shale gas exploration and development has attracted worldwide attention. Globally, mud and shale make up about 60% of the total sedimentary rocks, and shale gas resources have great prospects. The global shale gas resources are 456.24 × 1012m3. Mainly in North America, Central Asia and China, Latin America, the Middle East and North Africa, the former Soviet Union (Table 1).
