The Lacustrine Storm Deposit of Lower Youshashan Formation (N2xy) in Wunan Oil Field in Qaidam Basin

Abstract

Abstract: 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 N_2xy in this area. The finding of tempestite offers new targets for exploring the lithological oil-gas reservoirs in Qaidam basin.

Key words: Qaidam basin, Wunan oil field, Lower Youshashan formation, storm deposit, sedimentary structure
