【摘要】 以高分辨率率层序地层学理论为指导,通过对测井、录井、地震资料进行处理和变换,采用TOC、测井曲线与地层叠置样式、瞬时相位、时频分析等多种方法综合分析,井震结合,有效解决了CQ地区层序复杂界面识别困难的问题。建立了从馆陶组到沙四上层序地层格架,将主力含油层段——沙三上亚段划分为3个四级层序,并形成了一套适用于盆地边缘的测井、录井、地震相结合的层序地层界面识别方法体系。更多还原

【Abstract】 The sequence of the complex formation in CQ area are divided exactly by the combination of the TOC,superimposition style of the log and layer, instantaneous phase, time- frequency analysis, logging- seismic data and under the guidance of the theory of high- resolution sequence stratigraphy, The high resolution sequence stratigraphic frame from Ng to Es4 is established. The upper of Es3 which is the principle oil- bearing interval is divided into three bed successions of grade four. A system of recognition method to the boundaries of the basin is developed by the integration of the logging and seismic data.更多还原
