摘要
福特沃斯盆地Newark East页岩气田是美国第一大页岩气田,代表了一个集烃源岩、储层和盖层等成藏体系所有关键要素存在于同一套页岩层的非常规天然气藏——页岩气藏。根据研究资料,对福特沃斯盆地Barnett页岩气藏的特征进行了分析,包括页岩厚度、有机质类型及丰度、成熟度、孔渗和裂缝特征以及含气量等指标,重点研究了Newark East页岩气田的特征,该气田具有页岩层相对较厚、有机质丰度高、热成熟度高和被致密碳酸盐岩包围的特征。最后得出Newark East气田Barnett页岩气藏的气藏模式,并认为该页岩气藏的特征、模式在马拉松-沃希托、阿巴拉契亚逆冲褶皱带前缘的前陆盆地中具有普遍意义。
Barnett shale gas reservoir in Fort Worth Basin is the American biggest shale gas field which serves as essential factors of the petroleum accumulation system, such as source rock, seal rock, and reservoir existed in the same shale bed to a world-class unconventional natural gas accumulation (shale gas reservoir), is also the representative of American shale gas reservoirs. The paper studies the characteristics of Barnett shale gas reservoir in Newark East shale gas field. Barnett shale is relatively thick, organic rich, thermally mature, and enclosed by dense limestone units able to contain induced fractures. Also the research has obtained the shale gas reservoir model of Barnett shale. The gas reservoir characteristics and mode of Barnett shale gas reservoir should be of the universal significance in the foreland basin in the Ouachita and Appalachian thrust front.
