摘　　要：结合北黄海盆地的三维地震数据、测井和钻井资料,利用地震属性分析技术对该盆地东部坳陷中、新生代的储集层进行预测。结果表明,对该区储集层比较敏感的地震属性包括绝对振幅、复合绝对振幅、均方根振幅、能量值、振幅斜率和标准偏差。通过分析认为下白垩统和始新统的河流相为有利储集层,扇三角洲为较有利储集层。Based on the 3-D seismic and drilling data from the North Yellow Sea Basin, the technoIogy of multiple seismic attribute analysis was adopted to the Meso-Cenozoic reservoir prediction in the eastern de- pression of the North Yellow Sea Basin. The results suggest that the relatively sensitive seismic attributes to the North Yellow Sea reservoir include the absolute amplitude, composite absolute amplitude, RMS am- plitude, energy, amplitude slope and standard deviation. The absolute amplitude is related to granularity, the composite absolute amplitude and amplitude slope are indicators of sedimentary environment, the RMS amplitude shows the sand content, the energy indicates the water energy of the basin, and the standard de- viation illustrates the influence of tectonic movement and others. Through the seismic attributes analysis, it is concluded that the lower Cretaceous and the Eocene fluvial facies are the optimum reservoir and the fan delta is also considerable.
