摘要: 冷科1井是柴达木盆地一口深达5200m的科学探索井。多学科综合研究对比解决了该井井下地层的划分,统一了柴达木盆地东、西部其界线的对比。把柴北缘区半美星介、南星介井深标定到赛什腾凹陷1182-1179-1199地震测线上,为该区建立大区地层框架图提供了重要证据。

Abstract: Lengke-1 Well is a scientific investigation well with depth of 5 200 m. With the multidisciplinary research and correlation, the classification problem about in-situ strata in this well is solved, thus unifying or determining the borderline between eastern and western Qaidam basin. The well depth with Hemicyprinotus valvaetumidus and Australocypris in the northern margin of Qaidam basin is calibrated on the seismic line of 1182-1 179-1199 in Saishiteng sag. Prowiding a significant evidence for mapping the regional strati graphic framework in this area.

Key words: Qaidam basin, Lengke-1 Well, Paleogene, stratigraphic correlation, ostracoda, key fossil zone
