南阳凹陷西大岗露头区核桃园组沉积特征研究

Sedimentary Characteristics of the Hetaoyuan Formation in the Outcrop Area of Xidagang, Nanyang Sag

南阳凹陷的唐河西大岗露头是整个华北地区新生代含油气盆地中仅存的宝贵露头区,它的新生界露头剖面具有地质信息量大且连续性比较好的优势,因此成为南襄盆地以及华北地区研究新生代盆地沉积充填特征和油气生储盖组合的有利地区。桃园组是南阳凹陷的主要勘探目的层系,故对核桃园组沉积特征的研究有利于今后的油气勘探工作。

The Tanghe Xidagang outcrop in the Nanyang sag is the only remaining outcrop area in the Cenozoic petroliferous basins in the North China region.Its Cenozoic outcrop profile has the advantage of large geological information and good continuity.Therefore,it has become a favorable area for studying the sedimentary filling characteristics and the combination of hydrocarbon generation,reservoir and cap of the Nanyang-Xiangyang Basin and North China.The Hetaoyuan Formation is the main exploration target layer in the Nanyang Sag.Therefore,the study on the sedimentary characteristics of the Hetaoyuan Formation is conducive to future oil and gas exploration.
