Keyword:  伊洛瓦底盆地沙林凹陷石油地质生储盖组合成藏组合;
Abstract: 通过对伊洛瓦底盆地区域地质分析和沙林凹陷石油地质条件分析,认为凹陷油气成藏条件优越,始新统三角洲前缘亚相泥页岩和沼泽亚相煤系泥岩具有较强的生烃能力,为油气富集提供了丰富的物质基础,并与逆冲断裂带共同控制了油气田的分布;良好的生储盖配置、继承性圈闭及由断层、渗透层和不整合面共同构成的油气输导体系,为油气的聚集提供了运移通道和空间;良好的成藏配置关系形成了始新统-渐新统/中新统下生上储型成藏组合,主力含油砂体形成多重层状油气藏,待发现的始新统自生自储成藏组合主要位于逆冲断层下盘.凹陷北部D区块已在始新统塔本组发现该套成藏组合,沙林凹陷内具有相同的地层和构造圈闭特征,具有较好的勘探前景.
