摘　　要：陆架边缘三角洲自发现以来,因具有分布面积广、厚度大、储层发育等特点,在世界上已成为重要的油气勘探目标。结合国内外研究现状,通过研究国外典型陆架边缘三角洲和我国珠江口盆地珠海组陆架边缘三角洲的沉积特点,阐述了陆架边缘三角洲的识别特征,分析其对深水陆坡及海盆砂体沉积的控制作用并指出陆架边缘三角洲沉积对于深水油气勘探具有重大意义。Shelf-margin deltas have become an important hydrocarbon exploration target in the world for its wide distribution, big thickness and well-developed reservoirs. We made a brief review in this paper on the research status of the delta both at home and abroad,with emphasis on its depositional characteristics. The deltaic deposits developed in the Zhuhai Formation of the Pearl River Mouth Basin were taken and its role as examples in developm shelf-margin delta be of ~ We presented in the paper the identification criteria of a shelf-margin delta ent of sand bodies at continental slope and deep basin. Facts suggest that the great significance for the deepwater hydrocarbon exploration.
