摘要(Abstract)：

黄骅坳陷埕北低断阶沙河街组二段(简称沙二段)主要发育岩性油藏,储层砂体空间展布及控制因素认识程度较低。根据岩心观察、测井解释和地震属性数据,以及岩心物性化验数据和地震反演结果,结合研究区沉积背景及地理环境,确定研究区沉积特征和有利沉积微相,预测储层砂体。结果表明:沙二段处于断陷湖盆向坳陷湖盆转换时期,且埕北低断阶地形呈"多陡多缓、陡缓相间"格局,造成沙二段早期同时发育辫状河三角洲前缘和水下扇沉积,中期以浅水辫状河三角洲前缘亚相为主,晚期主要发育深湖相;沉积微相主要有水下分流河道、河口坝、前缘席状砂、支流间湾。受物源迁移、湖平面波动、地形差异及水动力条件不稳定等因素的影响,研究区沉积微相具有发育程度不一、微相形态各异、砂泥岩结构多变、垂向相序缺失等特点。水下分流河道和前缘席状砂发育规模较大,砂体储集物性较优;河口坝砂体发育程度较低;水下扇局部发育有利储层砂体。埕北低断阶沙二段中期浅水辫状河三角洲前缘亚相发育程度最高,主力砂体主要集中于研究区中东部,砂体叠合程度高,在近物源构造高部位砂体尖灭程度低,为储层砂体发育的有利区域。
