摘要(Abstract)：

根据岩心、测井、分析化验数据等资料,以大情字井油田黑60区块为例,研究三角洲外前缘薄层特低渗储层的岩相、构型要素、构型级别、砂体展布规律,建立外前缘的构型模式与识别方案。结果表明:外前缘岩相中的块状层理、平行层理、小型槽状交错层理、流水砂纹层理等与外前缘水道和砂坝伴生,泄水构造与包卷层理为三角洲前缘滑塌产生的浊积现象,复合层理的成因为局部水体的频繁进退、湖浪与沿岸流的改造、末端水道的交替溢出及湖泊假潮;外前缘构型具有基准面旋回明显、冲刷切割不明显、低比例朵体与低砂地比、朵体与席状砂共存等特征;与内前缘相比,外前缘泥岩为弱还原色—强还原色、水道化沉积发育较少、席状砂分布广泛、复合层理在砂质沉积中占50%以上,可容纳空间较大,沉降速率较小,能更完整保留整个基准面旋回,有较弱的砂体叠置关系与较低的砂地比,水道宽度较小、厚度较薄;与远砂坝相比,外前缘分选磨圆相对较差,朵体内正韵律与反韵律交替出现,朵体的展布多呈垂直或斜交岸线方向。
