    Identification and significance of the Paleocene-Eocene residual-slope sediments in western Qaidam Basin

    • 摘要: 提要:柴达木盆地新生代沉积特征复杂、相变快、岩性类型多样。本文从柴达木盆地昆北断阶带地质背景、岩心特征、岩石学特征等方面,系统地分析了昆北断阶带基岩上覆地层的岩性组合特征,确定其为残-坡积物。残-坡积物的新认识增加了柴达木盆地油气勘探的岩性油气藏新类型,为柴达木盆地基岩上覆地层的油气勘探提出了新的勘探方向。

       

      Abstract: Abstract:The Cenozoic Qaidam Basin has complex sedimentary characteristics, rapid transition of sedimentary facies and various types of lithology. The authors made a systematic analysis of the lithologic characteristics of the overlying strata of the bedrock in the North Kunlun step-fault zone from geological background, core characteristics and microscopic characteristics, and concluded that the sediments are residual-slope sediments. The new understanding of the residual-slope sediments has added a new type of oil and gas reservoirs for oil and gas exploration in the Qaidam Basin and pointed out a new direction for oil and gas exploration of the overlying strata in the bedrock of Qaidam Basin.
