摘　　要：涠西南凹陷位于北部湾盆地西南部,发育有多个油气田(含油气构造)。以油气地质理论为指导,在构造和沉积地层特征研究的基础上,重点分析了烃源岩、储集层、圈闭及输导介质等油气成藏的基本要素,认为涠西南凹陷拥有较好的烃源岩、发育多套储集层、多种类型圈闭和复合的输导介质,具备油气藏形成的基本条件,具有广阔的油气勘探前景。Many oil and gas fields or hydrocarbon-bearing structures have been discovered in Weixinan sag which is located in the southwest of Beibuwan basin. After we studied characteristics of the structures and sedimentary layers with the theory of petroleum geology, we gave our analysis results with the emphasis put upon oil accumulation elements such as source rocks, reservoir formations, traps, and transport media, and came to the conclusion that Weixinan sag has good source rocks, series of oil and reservoir formations, and abundant traps and transport media, and thus the sag possesses basic conditions for forming petroleum reservoirs and has cheerful prospect.
