摘　　要：针对垦东高凸起本身没有生烃能力 ,油气来源于周围的凹陷区 ,具有油源多、距离远 (5～ 4 5km)的特点 ,在对垦东地区油气成藏的基本条件烃源岩、储盖组合、圈闭类型及保存条件分析的基础上 ,重点对油气成藏的机制 ,包括生排烃过程、二次运移过程、有效运聚成藏系统进行了分析解剖 .指出油气聚集的最有利部位是高凸起潜山披覆构造带的相对低部位 ,具有储层厚度大、近油源、圈闭发育、油藏规模较大、丰度较高的特点 .并将垦东高凸起的成藏模式概括归纳为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 5～45 km.Based on the analysis of source rocks of four sags,reservoir cap rock combination,style of traps and preservation condition,the paper focuses on the research of oil/gas formation mechanism including the generation expulsion,secondary migration,effect migration accumulation system et al.It further points out that most good oil/gas accumulation part is located in the slope belt of Kendong high arch.Its characteristic is large reservoir thichnesses,good traps,near oil source bed ranges and large scale oil pools.Finaly the pool model is proposed for Kendong high arch.
