Abstract: 应用地质、地球化学、试油、钻井、测井等相关资料,对松辽盆地齐家地区上白垩统青山口组高台子油层高三、高四油层组致密油形成条件与分布规律进行了系统研究.本区致密油形成主要具备良好的烃源岩、储集层、源储配置及地层压力条件4个有利条件:青山口组一段、青山口组二+三段、嫩江组一段3套优质烃源岩为本区致密油的形成奠定了良好的物质基础;储集层条件较好,砂体类型多,主要有分流河道、河口坝、席状砂等,各类砂体累计厚度大,在平面上分布范围较广,连续性好,为致密油的形成提供了聚集空间;三角洲前缘相储集岩体直接与烃源岩接触或者呈指状尖灭于湖相烃源岩之中或者与烃源岩互层,提供了良好的源储配置条件;致密油储集层存在异常超压,压力系数分布在1.20~1.50,为致密油提供了成藏充注动力.研究表明本区高三、高四油层组致密油在平面上主要分布在凹陷的中心部位与凹陷周边的斜坡、阶地.
