上扬子地区早古生代页岩气与北美Barnett页岩气潜力对比

上扬子地区早古生代牛蹄塘组和龙马溪组发育两套分布广、厚度大、有机质含量高的页岩，目前相关的试验性页岩气开采较少，对其潜力缺少定量或相对定量方面的评估。北美地区Barnett页岩是页岩气开采历史最长，产量最高的页岩，建立了可靠的页岩气潜力的评价标准，对比评价上扬子地区早古生代页岩气潜力不失为经济有效的方法。通过比较发现，上扬子地区早古生代页岩与Barnett页岩具有相似的构造沉积背景和发育规模，二者之间具有很强的可比性。地球化学特征对比发现，上扬子地区早古生代页岩的有机质丰度、类型、成熟度、页岩气类型和有机质转化率等相关参数与Barnett页岩类似或更有利，认为其资源潜力不低于Barnett页岩，具有进行较大规模试验性开采的条件。

The Comparison of Paleozoic Shale-gas Potential in Upper Yangtze Area with Barnett Shale-gas in North America

In the upperr Paleozoic Niutitang and Longmaxi Formation there developed 2 sets of shales that were distributed widely in upper Yangtze Area,with big thickness,high content of organic matter.But the shale's exploration potential could not be quantitatively assessed as lack of experimental production.Barnett shale gas was the one with long production history and the highest production rate in North America,a reliable shale gas potential evaluation criteria were determined.So using these parameters to assess ...
