摘要：

南宫凹陷是由始新世、渐新世两期盆地叠置构成的凹陷。面积750km2。始新统生油岩已成熟,是主力生油岩。石油地质条件与近邻已获得油气藏的束鹿凹陷相似,有发现小—中型油气藏的前景。

Abstract:

The Nangong sag is a NNE-trending dust-pan shaped sag in southern Jizhong Depression.The remnant Paleogene measures 750 km2.The sag is a superimposed one composed of Eocene and Oligocene basins,the source rocks of which are Eocene and Oligocene sediments.It has similar petroleum geological condition as Shulu sag near by in which certain amount of hydrocarbon reserves have been found.This suggests that medium or small size of oil and gas fields could be found within the sag,and that Dagaocunarea in the sag should be focused as the main target.Structural-trapped pools may be found in the eastside of the area (fault-structural zone) and lithological-trapped pools may be found in the west side.
