[中国石化报油气周刊]中国工程院的评估显示,中国页岩气、致密气和煤层气技术可采资源量达31万亿立方米,为常规天然气可采资源量的1.5倍,开发利用前景令人鼓舞。然而,非常规天然气属于贫矿,开发难度大,经济性差,仍然面临政策、体制、技术等多方面掣肘,战略路线图模糊不清,大规模开发利用难以一蹴而就。 [China Petroleum & Petrochemical Weekly] According to the assessment conducted by the Chinese Academy of Engineering, the recoverable resources of shale gas, tight gas and coalbed methane in China are 31 trillion cubic meters, 1.5 times the recoverable amount of conventional natural gas. The prospect of development and utilization People encouraged. However, unconventional natural gas is poor in mineral resources. It is difficult to develop and economy is poor. It still faces many constraints such as policies, systems and technologies. The strategic road map is ambiguous and large-scale development and utilization are difficult to accomplish in a single step.
