环渤中地区新构造运动强烈,新近系是主要的含油层系.新近系勘探早期集中于凸起区和陡坡带,而斜坡带和凹陷区由于缺乏油气运移条件的系统性研究导致其勘探成效较差.基于前人研究和钻井资料,从分析环渤中地区新近系油气运移路径出发,通过建立“汇聚脊-断层-圈闭(脊-断-圈)”三元控藏模式,明确了受潜山风化壳汇聚脊控制的深层油气的汇聚能力是新近系油气富集的先决条件,并以圈闭面积为核心创建了聚油指数,用于定量评价深层油气的汇聚能力;明确了断层垂向运移是新近系成藏的关键,断层与汇聚脊、区域盖层的配置关系决定了断层的垂向运移量,当深层盖层的断接厚度小于220m时油气可运移至浅层;明确了圈闭因素是新近系成藏的最终环节,圈闭与断层的配置关系控制了浅层油气的侧向分流能力,其中,“双断型砂体”的侧向充注能力较强.“汇聚脊-断层-圈闭”三元控藏模式进一步丰富了渤海油田晚期成藏理论,在指导发现大—中型新近系油田以及其他他源层系的勘探中展现出良好的应用前景.
