摘要：

美国页岩气勘探开发目前已进入快速发展阶段,同时也带动了页岩地层内致密油的开发。文中所指的致密油,是指以吸附或游离状态赋存于渗透率极低的暗色页岩、泥质粉砂岩和砂岩夹层系统中的自生自储、连续分布的石油聚集。目前,美国致密油的开发集中在Bakken,Eagle Ford和Barnett页岩区带内。其中Bakken致密油资源量为230×108t,可采资源量为5.9×108t,待发现资源量为3.7×108t油及相近数量的伴生气,2000年至今累计产油约2800×104t;Eagle Ford致密油赋存于区带北部,年产油约20×104t;Barnett待发现石油平均资源量为1400×104t,待发现致密油资源量为480×104t,其北区主要产油、南区主要产气,目前拥有8000余口生产井,截至2009年底,"致密油带"累计产油量达770×104t。我国广泛发育富有机质页岩,致密油的勘探潜力较大。
