摘　　要：为了研究欢58块沉积微相的差异性,在区域特征及岩性、电性、沉积构造特征研究的基础上,分析绘制各砂岩组的沉积相平面图。研究表明,欢58块杜家台Ⅰ油组为浅湖时期河流入湖的扇三角洲前缘沉积,物源来自东北方向,砂体向西南方向展开,沉积微相发育形成水下分流河道、水下分流河道间以及河口坝。通过杜家台扇三角洲沉积微相模式研究,认为水下分流河道为研究区有利储集区域,也是井位部署的有利位置。In order to study the differences of sedimentary microfacies in Huan 58 area,we drew a floor plan of sedimentary facie of each sandstone group,based on regional characteristics,lithology characteristics,electrical characteristics and structure characteristics of the deposit. It turned out that Dujatai No. 1 oil group deposition is fan delta front at the period of shallow lake and the source is from northeast and the sand spread to southwest. The sedimentary microfacies included underwater distributary channel,inner distributary channel and mouth bar. Based on the research of fan delta micro- facies pattern of Huan 58 area,we can come to the conclusion that underwater distributary channel is the favorable reservoir area and is suitable for well deployment.
