页岩气是蕴藏于页岩层可供开采的天然气资源,中国的页岩气可采储量居世界第一。页岩气的形成和富集有着自身独特的特点,往往分布在盆地内厚度较大、分布广的页岩烃源岩地层中。较常规天然气相比,页岩气开发具有开采寿命长和生产周期长的优点,大部分产气页岩分布范围广、厚度大,且普遍含气,这使得页岩气井能够长期地以稳定的速率产气。 Shale gas is a natural gas resource available for exploitation in the shale layer. China has the largest amount of shale gas recoverable reserves in the world. Shale gas formation and enrichment have their own unique characteristics, often distributed in the basin thicker, widely distributed shale source rock strata. Compared with conventional natural gas, shale gas development has the advantages of long recovery life and long production cycle. Most of the gas production shales have a wide range of distribution, large thickness and generally gas-bearing, which enables shale gas wells to be stable Rate gas production.
