| 摘 要： | 综合利用286口探井的岩心、录井及测井资料,通过详细的沉积学分析,查明了松辽盆地北部西斜坡嫩江组一段发育的砂体是湖底扇.嫩江组一段S1砂组沉积时期,湖岸线在盆缘坡折附近波动时,受盆缘陡坡的控制,在西部斜坡形成了分布较为广泛的湖底扇.这种湖底扇的沉积特征是砂岩层夹在厚层暗色泥岩中,上下均呈突变接触关系.单层厚度大于2m的... |

| Abstract: | The data of cores,log and well logging of 286 wells were integrally used,through sedimentology analysis in detail,it was clarified that the sand bodies in K2n1 S1 Sand Group in the west slope of Northern Songliao Basin were caused by lake-floor-fan.During its depositional period,the lake-shore-line is fluctuated near the slope break of the basin margin,and it is controlled by the margin steep slope,the wide distribution of lake-floor-fan is formed in west slope.The depositional characteristics of the sandst... |
