摘要
根据垦东凸起原油及其周围生油凹陷烃源岩的色谱、色质等多种地球化学分析结果 ,确认了桩东凹陷沙三段是其最重要的油源凹陷 ,来自桩东凹陷的石油资源占该凸起总资源的四分之三以上 ,其次为沾化凹陷孤南洼陷和莱州湾凹陷 ,而青东凹陷的贡献很小。通过已知油藏分布的控制因素分析 ,总结了该区石油成藏条件及其富集高产原因 ,预测了油藏分布规律 ,指出了有利勘探方向。
Based on the results of geological analysis including gas chromatography and mass chromatography of oils from the Kendong Arch and source rocks in the surrounding sags, it is confirmed that the most important oil source is Es3 Member, Zhuangdong Sag, which contributes more than three-quarters of the total oil resource for the Kendong Arch; the second important sources are the Zhanhua Sag and Laizhouwan Sag, and the minor source is the Qingdong Sag. According to the controlling-factor analysis of known oil pool distribution, this paper describes the oil accumulation conditions and high-yielding wells in this area, forecasts the oil pool distribution patterns and points out favorite exploration targets. Research on oil-source correlation and oil accumulation conditions will provide valuable clues to oil pool formation in other similar areas of the Bohai Basin.
