| 摘 要： | 利用莺歌海盆地钻井中获得的丰富的有孔虫、钙质超微化石等微体古生物资料,对研究区新近纪各地层沉积时期的古环境及演化进行了研究。结合古环境及地震资料分析,重新认识了莺歌海盆地新近纪各层序界面。S40、S30、S28、S27等界面都具明显的峡谷侵蚀特征。另外,①号断层上升盘地层受峡谷侵蚀搬运后在下部S29界面上形成较好的储层,是下一步油气勘探的重要方向之一。

| Abstract: | Using the water water depth reconstruction based on the microfossil abundance and faunal composition from wells at the Yinggehai Basin of the northern South China Sea,we discussed the seismic boundary and re-evaluated the Neogene sequence stratigraphy in the Yinggehai Basin.The sequence interface S40,S28 and S27,are suggested to be of the canyon erosion;the uplifted wall offault No.1has undergone the process of canyon erosion and movement;and good reservoir for gas and oil is formed in the lower part of S29... |
