页岩气在中国发展应循序渐进

On Gradual Development of Shale Gas in China

页岩气储集层通常为低孔、低渗透率,开采寿命长,生产周期长,采收率变化较大,且低于常规天然气采收率,先进的开采技术使页岩气成为未来能源的希望。从理论研究、资源量评估、技术标准、钻完井压裂技术、国家政策、环境保护、天然气价格等方面分析当前中国开发页岩气的现状,得出目前中国还不适合大规模开采页岩气,其理论价值远大于工业价值。

Shale gas reservoir is characterized by low porosity and low permeability, long mine life, long production cycle, large changes in recovery and lower recovery ratio than conventional natural gas. Advanced mining technology makes shale gas hope of future energy. Shale gas development in the United States has achieved great success, setting off a worldwide wave of shale gas development. China has also opened its own shale gas exploration. From the theoretical research, resource assessment, shale gas standard, fracturing drilling and completion technology, public policy, environmental protection, natural gas prices and the analysis of other several aspects of the current status of development of shale gas it is concluded that large-scale exploitation of shale gas is not suitable at present in China.
