摘要
松辽盆地南部西部斜坡区为一东倾斜坡,断层及局部构造相对不发育,坡折带、湖湾及其大规模河口坝发育,具备形成大规模岩性油气藏的地质条件。该区超覆带的发现,为超覆地层油气藏的勘探指明了主攻方向。其成藏的关键因素则是局部盖层和侧向封堵条件。
The west slope of the south of Songliao basin is a great slope inclining to the east which has few faults and structural traps. Slop-break belt, lake bay and great river mouth bar developed are very favorable for subtle reservoir. Especially, the overlap belt found is an important exploitation field for stratigraphical overlap reservoir. The key factor of subtle reservoir formation is local cap rock and lateral sealing layer in this region.
