| 摘 要： | 本文应用层序地层学方法，通过钻井、测井、古生物、野外露头剖面、勘探线等的分析, 将准噶尔盆地南缘侏罗系中下统划分为1个三级层序，并以地层叠置样式、岩性、岩相的变化细分出低位、湖侵和高位体系域，在连井剖面层序对比的基础上建立了研究区三工河组层序地层格架。通过钻井、测井、古生物、野外露头剖面等资料的分析识别出侏罗系中下统主要发育扇三角洲、三角洲、湖泊、沼泽等主要相类型，并首次系统分析了准噶尔盆地南缘三工河组沉积相的构成、演化与分布规律,这对于指导研究区煤炭、油气的勘探具有重要意义。 |

| Abstract: | This paper applies sequence stratigraphy method, based on drilling, logging, paleontology, outcrops and prospecting lines, classifies the lower to middle Jurassic in southern Junggar basin into one grade III sequence, and establishes a sequence stratigraphical frame of Sangonghe formation by using stratigraphical overlapping patterns, lithology, lithofacies, and profiles comparison. The lower to middle Jurassic basically comprises fan delta, delta, lakes, and morasses. This paper analyzes systematically the components, evolution and distribution of Sangonghe formation in southern Junggar basin, offering a reference in coal and oil-gas exploration in this study area. |
| Keywords: | southern margin of Junggar basin Sangonghe formation sequence sedimentation |
