| 摘 要： | 南阳凹陷是一个单断式的南深北浅的箕状断陷。核二段沉积时期是南阳凹陷的主要沉降期，沉积物源主要来自西北方向的师崩凸起和东北的社旗凸起，其次来自南部的新野凸起。通过对储层岩石学特征的研究，识别出不同的沉积相标志。认为南阳凹陷东部地区核二段主要发育2种沉积相，即北部斜坡带的三角洲相和南缘凹陷边界断层的水下冲积扇相。根据不同沉积微相的测井响应特征，研究了沉积相在平面上的分布特征，并总结出研究区的相层序和相模式。

| Abstract: | Nanyang Sag is a single-fractured dustpan-like one where the south is deep and the north is shallow. The second member of Hetaoyuan Formation was formed in the main subsidence stage of Nanyang Sag. The source materials mainly came from the Shigang uplift in the northwest and the Sheqi uplift in the northeast as well as Xinye low uplift. Different markers of the sedimentary facies are distinguished through the research of the reservoir petrologic characteristics. The second member of Hetaoyuan Formation in the east of Nanyang Sag mainly occurs in two sedimentary facies: the deltaic deposit on the northern slope belts and the subsea alluvial fan deposit on the southern boundary fault. Based on the log response of different sedimentary microfacies, the distribution character of the sedimentary facies in the plane is researched, and the facies sequence and pattern of this area are summed up. |
