鄂尔多斯盆地陇东地区长8油层组物源分析
Provenance analysis of Chang 8 oil-bearing formation in Longdong area,Ordos Basin
摘要
Abstract
There is a significant controversy over the source of sediments from Yanchang Formation in Longdong area of Ordos Basin,especially in western region.To explore the provenance of Chang 8 oil-bearing formation,comparitive analysis of the characterization of the peripheral native rocks in Longdong area,the distribution characteristics of light minerals,rock debris,heavy mineral,as well as ancient water flow,rare earth elements comparison are studied.The results show that the provenance zoning of light minerals,rock fragment,and heavy minerals in Chang 8 oil-bearing formation in Longdong area shows good consistency.The Chang 8 oil-bearing for-mation is controlled by multiple provenances,the primary provenances are the southwest and northeast prove-nances,and the secondary provenance is the northwest,west,and south provenance.Each provenance conver-ges near the area of Fanjiachuan-Huachi-Anzhi farm.The Hexi Corridor area of Yanchang Formation has a cer-tain connectivity with Ordos Basin.The western provenance supply is dominated by the source area of Hexi Cor-ridor,supplemented by Haiyuan ancient uplift,and the two are superimposed.关键词
