| 摘 要： | 通过对莺歌海盆地和琼东南盆地天然气、凝析油的地球化学特征分析，认为莺歌海盆地底辟带天然气主气源为上第三系梅山组，三亚组海相泥岩，YC13－1气田天然气主气源为下第三系陵水组，崖城组滨海沼泽及 浅海相源岩，有机包裹体，成岩作用和天然气分布等研究结果表明，莺歌海盆地底壁带天然气为多期幕式充注，最晚一期为富含CO2天然气的充注，YC13－1气田天然气总体上为连续充注。

| Abstract: | Based on the analysis about geochemical characteristics of gases and condensates in Yinggehai and Qiongdongnan Basins, it is believed that the gas in diapir zone of Yinggehai Basin mainly derives from Neogene Meishan and Sanya Formation source-rocks, and that the gas of YC13-1 gas field mainly derives from Paleogene Lingshui and Yacheng Formation source-rocks. According to organic inclusion, diagenesis and gas distribution, it is suggested that the gas in diapir zone of Yinggehai Basin has been charged in multiple episodes, with the latest charging rich in CO2. In YC13-1 gas field, however, the gas is charged continuously in general. |
