摘要
合浦盆地是中国南方有代表性的盆地，其下第三系发育有酒席坑组和上洋组二段两套生油岩系。西场、常乐两个凹陷既有相似性、又有各自特点。文章在研究其沉积环境、物源及有机质演化特征的基础上，确定该盆地成熟门限深度，表明合浦盆地具有良好的油气勘查前景。
Hepu basin is a reprentative basin in south China, there are two source rock series ( Jiuxikeng formation and two members of Shangyang formation) in its lower tertiary system. Xichang and Changle depressions in the basin not only have some similarities, but also possess their respective characteristics. On the basis of study on its sedimentary environment, sources and evolution characteristics of organic matter, this paper ensures the mature threshold depth and shows good prospects in oil and gas exploration in Hepu basin.
