摘要(Abstract)：

渤海油田新近系河流相储层是渤海油田增储上产的主力开发层位之一,海上河流相储层开发面临储层厚度薄、横向变化快和井网稀等问题。以垦利3-2油田3-1483砂体为例,应用正演约束叠后地震资料谱反演技术,研究细分成因单元的储层精细构型;根据地震相典型特征,识别水下分流河道的4种接触模式,即分离式水下分流河道,叠置、切割式水下分流河道,叠置式水下分流河道和连接式水下分流河道;利用地震剖面及地震资料谱反演技术,将垦利3-2油田较为复杂的3-1483砂体纵向上精细划分为2期,平面上精细划分为4条河道砂。9口开发井的井位实施结果表明:比优化前减少低效井4口,注采对应率由优化前20%提高到80%,能够解决以垦利3-2油田为代表的海上复杂河流相油田开发早期储层精细刻画问题,为渤海类似油田的开发提供技术借鉴。
