| 摘 要： | 在层序地层学和沉积学理论指导下，以油气勘探为目标，根据岩芯观察、岩石薄片鉴定分析、测井资料、地震资料，确定珠江口盆地（东部）珠江组主要发育：（1）碎屑岩沉积体系一三角洲、滨岸和浅海相；（2）碳酸盐岩沉积体系一开阔台地、台地边缘及台地前缘斜坡相。通过暴露标志、岩性岩相组合、生物组合及测井为主的层序界面识别，将珠江组划分为4个三级层序。在此基础上，对珠江口盆地（东部）珠江组取三级层序体系域或三级层序为成图单元，进行层序岩相古地理编图，详细探讨了珠江口盆地（东部）珠江组古地理特征及演化。结合各相带储集物性特征，认为珠江组SQ1-HST、SQ2-HST及SQ3晚期形成的台缘、台内礁滩沉积是寻找有利储集层的重要储集相带。

| Abstract: | With the aid of sequence stratigraphic and sedimentological theories and in integration with core observation, thin section examination, well logs and seismic data, the Zhujiang Formation in eastern Zhujiangkou Basin may b divided into： （1） the siliciclastic depositional system including delta, littoral and shallow marine facies, and （2） carbonate depositional facies. Four third-order sequences have system including open been distinguished for platform, platform-margin and platform foreslope the Zhujiang Formation on the basis of exposure indicators, lithologic association, organic association and well logs, and sedimentary facies and palaeogeographic maps are constructed according to the systems tracts of the third-order sequences or the third-order sequences. The platform-margin and intraplatform reefal （bank） deposits formed during the deposition of the SQ1-HST, SQ2-HST and SQ3 sequences are considered as the favourable zones for hydrocarbon accumulation in the study area. |
