摘　　要：文章针对垦东高凸起本身没有生烃能力 ,其油气来源于周围凹陷 ,具有油源多、距离远 ( 5～45km)的特点 ,从成藏动力学系统出发 ,在分析讨论了垦东高凸起成藏动力学系统成藏条件和特点的基础上 ,将垦东纵向上划分出 5个成藏动力子系统 ,平面上划分出 4个成藏动力亚系统 ,并分析讨论了成藏动力亚系统的动态演化特点和成藏模式 ,指出桩东—垦东成藏动力亚系统虽运移距离远 ( 1 0～45km) ,但由于动力强 ,砂岩疏导层、不整合面和断层共同组成的联络体系发育 ,圈闭条件好 ,成藏时期长 ( 1 0Ma) 。Kendong high arch is only covered by the Upper Tertiary. There are no oil source beds. Its oil/gas comes from four surrounding sags and the distance is far about 5～45km. Based on the analysis to oil/gas formation conditions of dynamics system of Kendong high arch, five oil/gas formation dynamics order systems in vertical are divided and four oil/gas formation dynamics sub-systems in lateral are recognized. The dynamics evolution process and oil/gas formation model are discussed. Finely the paper point out that most good oil/gas formation dynamics sub-systems is Zhuangdong-Kendong oil/gas formation dynamics sub-systems, which has high power, developed migration system, good traps and longer oil/gas formation time (10Ma).
