摘　　要：针对辽东湾盆地旅大10-1油田建立精细地层格架并确定沉积微相类型及沉积模式,对于该油田的开发十分必要。研究表明:旅大10-1油田东营组东二下段Ⅱ和Ⅲ油组分别对应2个中期下降半旋回,沉积物源来自西北方向,主要有2个分支水道向该盆地供源,形成辫状河三角洲前缘水下分流河道、河口坝和席状砂等沉积砂体;Ⅱ油组的砂体厚度较大,对应的小层砂体厚度一般大于10 m,全区均有分布,且砂体顺物源方向延伸约2 000 m;Ⅲ油组的砂体沉积较少,厚度较薄,对应的小层砂体厚度一般小于8 m,砂体顺物源方向延伸约1 000 m。To establish the fine stratigraphic framework and definite the sedimentary microfacies and depositional model of LOda 10-10ilfield is necessary for field development. Oil group Ⅱ and Ⅲof the under second member of Dongying Formation are corresponding to two middle-term declining hemicyele in Ltida 10-10ilfield, sediment source came from northwest provenance, sediments followed two main branches of watercourses towards the basin, and formed underwater distributary channel, mouth bar and sheet sands deposition within braided river delta front. S/rod body thickness of oil group Ⅱ is great, sand body thickness of the small layer is generally greater than 10 m, the sand bodies distribute in the whole region, from northwest to southeast, and along the direction of sediment source, sand bodies extend up to 2 000 m. The sand body thickness of oil group Ⅲ is thinner, sand body thickness of the small layer is generally less than 8 m, and sand bodies extend about 1 000 m along the direction of sediment source.
