摘　　要：利用钻井、测井及地震资料,通过对珠江口盆地(东部)大量的岩心和薄片的观察鉴定以及对地震剖面资料的精细解释,进而探讨珠江组碳酸盐台地的沉积特征与地震响应特征.珠江口盆地(东部)碳酸盐岩由于古地貌及海侵时间的差异性,珠江组沉积序列,特别是碳酸盐台地的沉积厚度及发育时间,存在明显的差异性.碳酸盐台地沉积相带发育齐全,包括:开阔台地、台地边缘及其台地前缘斜坡3类沉积相.碳酸盐台地的地震相特征突出,易于识别.Based on drilling, logging and seismic data, large number of cores in Pearl River Mouth Basin （Eastern） and slice identification, and seismic data interpretation, we discusses the pearl river group of carbonate platform sedimentary characteristics and seismic response characteristics. Due to ancient landform and transgression time difference, the sedimentary sequence of Pearl River group, especially the carbonate platform sedimentary thickness and development time, the carbonate in Pearl River Mouth Basin （Eastern） has an obvious difference. Sedimentary faces of carbonate platform development are complete, including： open platform, platform edge and three kinds of sedimentary faces of platform front slope. The characteristic seismic facies of the carbonate platform is prominent, easy to identify. The results show that the favorable reservoir faces distributes in platform margin reef and horn dust beach.
