通过对准噶尔盆地阜东斜坡区头屯河组沉积背景分析，认为研究区存在北东部卡拉麦里山和南部天山2个物源，区内NE向凸起及沟槽对水系具分隔控制作用。基于钻井岩心观察及单井相、地震资料综合分析，认为本区沉积相类型主要为三角洲相。运用地质地震结合方法，确定本区头屯河组主力油层段的平面沉积特征，即阜北及白家海地区以三角洲平原沉积为主，阜东5井区以三角洲前缘沉积为主，湖泊相沉积主要位于凹陷中心。

Based on analysis of depositional background, it is considered that the NE-trending bulges and grooves con-trolled drainage of Toutunhe formation 2nd member on East Fukang slope of Junggar basin. The study area exist two provenaces, include the Kelameili provenace form north-east and South provenace form Tianshan. The integration of da-ta on core analysis, well-facies, seismic data, several Delta sedimentary microfacies types identified in the study area. Af-ter analyzed geological and seismic data, sedimentary facies were found in the Fudong slop, that is North of Fukang de-pression and Baijiahai region dominated delta plain, Fudong-5 well area are delta front deposits, lake sediments are main-ly located in the depression center.
