| 摘 要： | 以层序地层学理论为指导，通过对准噶尔盆地车排子地区新近系沙湾组地质、地震、钻井、测井及露头等资料的综合分析，将新近系沙湾组从下向上依次划分为两个三级层序：沙湾组层序一和沙湾组层序二，共识别出 3 个三级层序界面。通过对不整合面、整合面、初次湖泛面和最大湖泛面等各级湖泛面的识别和对比，从层序的划分入手，对体系域、准层序组等边界的识别特征进行了较深入的分析，建立了研究区新近系沙湾组的等时地层格架。

| Abstract: | Based on the sequence stratigraphy theory, through the comprehensive analysis of geological, seismic,drilling, logging and outcrops of Neogene Miocene Shawan group strata of Chepaizi Area in the Junggar Basin,Neogene Shawan group can be divided into two third-sequences from the bottom to the top: N1SSQ1 and N1SSQ2.A total of 3 third-sequence boundaries are identified. Through identifying and comparing the unconformity surface,conformity, the initial lake flooding surface and the largest lake flooding surface, etc., beginning with the study of sequence division, the identifying characteristics of the system tract and parasequence sets boundary are analyzed deeply, the isochronous sequence stratigraphic framework of the study area is set up. |
