辽河红星地区沙一段储集砂体展布特征研究
|
摘要
以层序地层学及沉积学等理论为指导,综合区域地质、地震、测井及岩心资料分析等,在辽河油田红星地区开展层序地层和沉积体系研究。在已有的区域层序地层格架内,识别出三角洲前缘水下分流河道、河口坝、前缘席状砂坝、分流间湾和滨浅湖等多种沉积微相类型,并总结了各种沉积微相的测井响应特征,进一步探讨了沙一段有利储集相带的分布规律。结合四级湖平面变化,同沉积断裂,火山活动,沉积相分布等,分析了沙一段砂体分布的控制因素。
In the reference of sequence stratigraphy and sedimentology,this thesis combined with regional geological materials,seismic and well-logging data,it launched the research of the sequence and depositional system.Based on the establishment of regional sequence stratigraphic framework,it identified several depositional microfacies such as the underwater distributary channel,river mouth bar,sheet bar,interdistributary bay,shallow lake and so on.It also concluded the well-logging characters of different depositional microfacies.Furthermore,it probed into the distribution rules of favorable reservoirs of Es1 in Hongxing Area.In terms of the 4th lake-level changes,syndepositional faults,volcanic activity and sedimentary facies distribution,the dominant factors for Es1 sandstones distribution are analyzed.
