松辽盆地高台子地区扶杨油层组是典型的浅水型陆相三角洲沉积, 沉积体主要由三角洲平原分流河道和三角洲前缘水下分流河道组成, 主要沉积体和河流沉积具有一定的相似性, 该文以Miall 的河流结构要素分析法来研究该区目的层, 识别出13 种基本岩相, 在岩心沉积体内部识别出1～5 级沉积界面, 划分出具有成因意义的7 种构形要素: ①分流河道; ②顺流加积底形; ③侧向加积沉积体; ④单一侧积砂层; ⑤纹层砂席; ⑥砂底形; ⑦越岸细粒沉积。这些构形要素对扶杨油层组的沉积研究提供了直观的依据。

Fuyang Formation in Gaotaizi area，Songliao Basin is typical shallow water continental delta deposits. These deposits are mainly composed of delta plain distributary channel and delta front subsea distributary channel，and similar to river deposit. Based on the study on the target layer by Miall′s structural element analysis, thirteen types of basic lithofacies were identified, depositional interface from 1st to 5th order were identified in the core deposit, and seven kinds of architectural elements with genetic value were divided，including distributary channel, downcurrent accretion bed form, lateral accretion deposit, single lateral depositional bed, laminated sand sheet, sand bed form and overbank fine sediment. These elements provide evidence for the sedimentary study on Fuyang Formation.
