摘要
为了进一步明确柴达木盆地阿尔金山前东段的牛东鼻隆钻遇地层的地质时代,对牛东地区约20口井做孢粉分析、鉴定研究,梳理了该区的孢粉组合序列。选取具有代表性的牛1、牛2、牛3、牛102四口井,通过其孢粉化石组合特征,建立了2个孢粉化石组合,确定了牛东地区的地质时代。
In recent years,with the increase of oil and gas exploration in the front of Altun Mountain in Qaidam Basin,Niudongbilong,located in the eastern part of the front of Altun Mountain,encountered the Jurassic.In order to further clarify the geological age of this set of strata,sporopollen analysis and identification were carried out in about 20 wells in Niudong area,and the sporopollen assemblage sequence in this area was sorted out.In this paper,two sporopollen fossil assemblages of Niu 1,Niu 2,Niu 3 and Niu 102 wells are established and the geological age of Niudong area is determined by their sporopollen fossil assemblage characteristics.
