摘要： 依据砂岩阴极发光、锆石阴极发光形态及锆石测年等资料对舞阳凹陷核桃园组的物源进行了分析,证实舞参3 井和舞 8 井核二段的物源来自于舞阳凹陷的南缘,与前人认识完全不同,即核桃园组沉积时期凹陷南部斜坡辫状河三角洲砂体向凹陷内部推进距离远,凹陷北部陡坡带扇三角洲砂体沿边界断裂分布。上述认识对指导舞阳凹陷油气未来勘探部署具有十分重要的意义。

Abstract: In this paper, the zirconite cathodeluminescence and dating data are used to analyze the provenance of Hetaoyuan formation in Wuyang sag. It is firstly confirmed that the provenances of He-2 sections in Well Wucan-3 and Well Wu-8 are all from the southern margin of the sag. Namely, the sand bodies of braided river delta in the southern slope of Wuyang sag in the period of Hetaoyuan formation moved far toward the inner sag and those near the northern steep slope distributed along the boundary fault. This discovery plays a key role in petroleum exploration and deployment of Wuyang sag in the future.

Key words: Wuyang sag, Hetaoyuan formation, provenance analysis, cathodeluminescence, zirconite dating
