在对地表露头的微相分析基础上,对阜康地区水西沟群进行高分辨率层序地层学研究。在水西沟群内识别出由V级层序界面控制的短期基准面旋回层序,在此基础上,根据短期基准面旋回层序的垂向序列、岩性岩相组合、结构类型及叠加样式等特征,对研究区水西沟群中期、长期基准面旋回层序进行了划分,其中中期基准面旋回层序8个,长期基准面旋回层序4个,最终建立了研究区高分辨率层序地层格架,对该地区的油气勘探工作有一定指导作用。 Based on the micro-facies analysis of surface outcrops, the high-resolution sequence stratigraphy of Shuixigou Group in Fukang area was studied. Based on the short-term base-level cycle sequence controlled by the V-sequence sequence interface, the vertical sequence of lithologic sequence, lithology and lithofacies assemblage, structure type and superposition Style and other characteristics of the study area, the mid-term and long-term basal-level cycles of Shuixigou were divided. There were 8 mid-level cycles and 4 long-term cycles. Finally, the high resolution Sequence stratigraphic framework, the oil and gas exploration in the region have a guiding role.
