摘　　要：大港油田K46滚动开发区地震地质条件复杂,储层物性变化大,储层与非储层在声波曲线上没有明显的差异,为此,在该井区采用了基于模型的特征曲线重构地震反演技术——SP曲线重构.反演预测结果表明储层的可辨识性与反演结果的可靠性得到明显的提高,并获得显著的地质效果.Based on complicated condition of seismic-geology in K46 rolling developmental block, varied quickly reservoir's porosity and no-difference clearly for reservoir & no-reservoir in sonic log ,DaGang OilField, so the researchers apply constructed-log seismic inversion technology of geophysical reservoir attribute by model - SP constructed-log.The results of seismic inversion and predicted reservoir proves that reservoir's identification and inversion's truth raise obviously, Moreover obtain geological effect.
