摘要
Appalachian盆地位于美国东北部,是美国石油工业的发源地,也是目前美国页岩油气资源勘探开发的主要盆地之一。其中泥盆系Marcellus页岩气区带目前已成为北美页岩气资源量最大的页岩气藏,也是北美多家石油公司页岩气资源勘探开发的主要焦点。文章分析了Appalachian盆地沉积构造演化、油气地质特点,重点解剖了盆地Oiho、Marcellus、Utica三套页岩油气区带的成藏特征,分析了三套页岩的厚度、有机质类型及丰度、成熟度、孔渗、裂缝的特征等参数以及成藏主控因素,并对未来勘探有利区和开发潜力进行了客观评价。
Appalachian basin which is located in the North-eastern US is the origin of America＇s petroleum industry,and also one of major basins for shale-gas exploration. The Devonian Marcellus shale-gas becomes the biggest shale-gas reservoir in the North America,so it is the target for North America＇s oil companies. This paper analyzes its sedimentary and structural evolution,oil-gas geology,and focuses on Oiho,Marcellus and Utica zones in their reservoir formation from shale thickness,organic types and concentration,maturity,porosity,and fissures,and evaluates their potential for future exploration and development.
