摘要
柴达木盆地乌南油田下油砂山组(N2xy)为湖相风暴沉积,岩心观察、岩石薄片鉴定结果表明,研究区风暴沉积构造丰富,主要有:冲刷面、渠模、泄水构造、生物逃逸迹等。建立了研究区N2xy地层风暴沉积序列,风暴岩的发现将为柴达木盆地寻找岩性油气藏提供新的方向。
The results from core observation and thin-section analysis show that the lacustrine storm sedimentary structures are rich in Wunan oil field in Qaidam basin,such as scour surface,gutter cast,runoff structure,biological escape trace,etc.This paper presents the storm sedimentary sequence of N2xy in this area.The finding of tempestite offers new targets for exploring the lithological oil-gas reservoirs in Qaidam basin.
