摘要
应用高分辨率层序地层学理论,综合岩矿学、生物地层学、地球化学和地球物理资料,对齐家地区青山口组二三段高台子油层进行高分辨率层序地层研究,以具体单井的岩心、测井等信息着重指出了齐家地区高台子油层高分辨率层序地层划分的识别标志,在齐家地区高台子油层高三、高四油层识别出两种界面类型,并以此为基础在高三、高四油层组划分了1个长期基准面旋回、5个中期基准面旋回、19个短期基准面旋回。在中期基准面旋回划分的基础上对研究区域沉积相平面分布特征做了相应分析,清晰的显示了齐家地区青一段到青三段沉积体系由水进到水退不断向盆内推进的地质过程。
According to the high resolution sequence stratigraphy＇s theory and the information of rock-mineral analysis, biological stratigraphy, geochemistry and geophysics, a systematical and in-depth research on high resolution sequence stratigraphy Of Gaotaizi reservoir of Qijia area in Songliao basin was carded out. Identification marks of sequence boundary for sequence division of GaoTaiZi reservoir was pointed out emphatically, and two kinds of boundaries were recognized on G3, G4 oil layer group of Qijia area, which was used as the basis to divide G3, G4 into 3 partition, Then characteristics of each base level and distribution of sedimentary facies were analyzed.
