摘　　要：为了查明扇三角洲前缘储层构型特征与分布模式,以辽河盆地欢喜岭油田锦99区块杜家台油层为例,综合储层构型理论与高分辨率层序地层学研究方法,应用岩心、测井及录井资料,分析了扇三角洲前缘储层构型单元的特征,明确了构型界面的分级系统,建立了单砂层级构型界面的定性识别标准与定量判别模式。研究结果表明:扇三角洲前缘储层中3级、4级构型界面是单砂层内主要的渗流屏障,控制着剩余油的形成与分布。4级构型界面主要为洪泛泥岩、辫状水道顶部泥质层以及河口坝顶部落淤泥,3级构型界面常为砂体顶部的细粒沉积与单期辫状水道底部滞留沉积,二者均具有较明显的测井响应特征。In order to find out the architecture characteristics and distribution mode of fan-delta front reservoirs,taking Dujiatai reservoir of Jin-99 block in Huanxiling Oilfield of Liaohe Basin as an example,the characteristics of the architecture units of fan-delta front reservoirs are analyzed,the grading system of architecture interfaces is proposed and the qualitative identification standard and the quantitative determination mode for the architecture interfaces of single sandbody are established according to core and well logging data based on reservoir architecture theory and high-resolution sequence stratigraphy. The research results show that the third and the fourth grade architecture interfaces in fan-delta front reservoirs are main seepage barrier in the single sandbody,and they control the formation and distribution of remaining oil. The fourth grade architecture interfaces mainly include the flood shale,the argillaceous layers on the top of braided river channel and debouch bar. The third grade architecture interfaces mainly include the fine grained sediment on the top of sand-body and the lag deposit in the bottom of single braided river channel. Both of them have the distinct logging response characteristics.
