随着北美页岩气的勘探开发获得巨大成功,中国也掀起页岩气勘探开发的热潮。页岩气一般分布于沉积盆地的斜坡和中心带,具有工业开采价值的页岩气一般产自有机质丰度高、脆性矿物含量高、存在异常高压的页岩地层。本文通过深入分析我国页岩气的储层类型,对比不同沉积环境,不同储层类型,不同有机质等多个因素对页岩气的影响,并结合北美对页岩气的发展情况,找到制约我国页岩气发展的因素。
With the tremendous success of North American shale gas exploration and development, China also started a boom in shale gas exploration and development. Shale gas is generally distributed in the slope and central zone of the sedimentary basin. Shale gas with industrial exploitation value is generally produced from shale formations with high abundance of organic matter and high content of brittle minerals and abnormally high pressure. In this paper, by deeply analyzing the types of shale gas reservoirs in China and comparing the influence of different sedimentary environments, different reservoir types and different organic matters on the shale gas, combined with the development of shale gas in North America, Shale gas development factors.
