【摘要】 应用层序地层学基本理论,在综合分析工区地震、测井、岩心等资料的基础上,确立了超层序界面、准层序和准层序组识别标志,进而对松辽盆地北部升平地区深层进行超层序界面识别,共识别出五个超层序界面(四个超层序),分别为基岩顶面(SSB1)、沙河子组底面(SSB2)、营城组底面(SSB3)、登娄库组底面(SSB4)和泉头组底面(SSB5)。从而建立了升平地区深层层序地层格架,并且对两个重大不整合面(SSB1和SSB4)的地层超覆不整合圈闭及其分布范围进行了预测。更多还原

【Abstract】 Based on seismic, well logging, drilling and core data, five super sequence boundaries have been identified by using methods of sequence stratigrphy theory in deep formations of Shengping area, northern part of Songliao basion. They are the top boundaries of bed rock (SSB1), the bottom boundaries of Shahezi group (SSB2), the bottom boundaries of Yingcheng group (SSB3), the bottom boundaries of Denglouku group (SSB4) and the bottom boundaries of Quantou group (SSB5) respectively. Then sequence stratigraphic frameworks in deep formations of Shengping area were established. Furthermore, the overlap unconformable traps and their distribution ranges of two important formations surface (SSB4和SSB1) were predicted.更多还原
