摘　　要：大港滩海地区各区块增储,上产的重、难点问题是储层分布问题,少量的钻井资料难以准确反映储层分布,结合本区所需,基于地震属性的解释方法可以较好地认识储层分布。该方法运用以敏感地质要素为指导,以优选属性、合理确定时窗类型及时窗大小为基础的解释方法,通过属性研究落实沉积砂体分布,指导了滩海地区水平井实施。滩海地区属性研究表明,在未受后期构造强烈改造的深层,属性刻画砂体效果显著;属性应用关键是对地质要素的掌握及与地震的结合。Reservoir distribution is a key problem in offshore area of the Dagang oilfield. It is difficult to accurately reflect the distribution of reservoir with a small amount of drilling data. According to the needs of this area,the reservoir distribution can be obtained by seismic attributes. With sensitive geological factors as guidance,with optimal attribute,reasonable time window type and time window size as basis,the distribution of sedimentary sand body is made clear by seismic attributes,thus successfully guiding the implementation of horizontal wells in offshore area. Researches in offshore area show that in deep layer of the sand body which is not strongly transformed by the late tectonic activity,the attribute description of sand body has notable effect. The key to attribute application is to grasp the geological elements and seismic data.
