摘要(Abstract)：

西湖凹陷中北部地区面积广,井点和取心数量少,导致花港组物源和沉积相类型认识存在争议。根据砾石成分、岩屑类型、石英阴极发光特征和重矿物组合类型,判断研究区母岩的主要岩石类型;根据重矿物ZTR指数,判断沉积物搬运距离;根据倾角测井和地震前积反射结构特征,推断古水流方向;根据泥岩颜色、泥砾特征、层理类型、粒度概率累积曲线和岩石类型等相标志,判断沉积相类型。结果表明:研究区花港组物源主要来自北部的虎皮礁凸起,局部有东部钓鱼岛隆褶带物源的混入;发育辫状河三角洲前缘亚相,包括水下分流河道、河口坝和水下分流间湾3种微相类型,其中以水下分流河道微相为主。该结果可以为西湖凹陷中北部地区勘探和开发提供指导。
