【摘要】 本论文以层序地层学、沉积学、石油地质学等理论为依据，应用地震、录井、岩心等资料，分析莺山—庙台子地区登娄库组至泉二段层序地层格架特征、沉积相分布、储盖组合特征及构造圈闭等特征。综合层序地层学原理，结合地震上不整合特征及测井、岩心上的变化特征，依据井间对比的原则，实现了登娄库组、泉一二段顶底界面的地震分层与钻井分层相对应，建立了研究区登娄库组至泉二段层序地层格架。研究区共识别出7个三级层序界面，自下而上分别为：登娄库组底界面、登二段底界面、登三段底界面、登四段底界面、泉头组底界面、泉二段底界面、泉二段顶界面，其中登娄库组底界面、泉头组底界面、泉二段顶界面为超层序界面。本文认为登娄库组是一个超层序，超层序内部包含4个三级层序，将泉一二段划分为一个超层序，超层序内部划分2个三级层序。对各三级层序进行了体系域的划分。通过制作地层厚度图和等t0图，对地层厚度分布特征进行了分析，并对地层格架内的层序界面的构造特征进行了研究。研究区圈闭类型以背斜、断背斜和断块圈闭为主。通过进行单井相、联井相分析，总结研究区共识别出5种大相、21种亚相、38种微相；此外针对研究区的特点，刻画出了7张三级层序的沉积微相图，并且总结出登娄库组、泉一二段沉积演化规律。根据生储盖特征将登娄库组至泉二段地层划分为三套储盖组合，分析了本区的有利勘探区带。更多还原

【Abstract】 Guided by the theories of sequence stratigraphy,sedimentology,petroleum geologytheory,using seismic data,well logging,cores information in the the the Yingshan-Miaotaiziarea Denglouku Group-Members2of the Quantou,research and analysis on the sequencestratigraphic framework,sedimentary facies,reservoir structural traps in the study area havebeen carried out in the paper.Integrated application of sequence stratigraphy principles, combined with the seismiccharacteristics of unconformity and logging curves,variations on the core,based oncomparison between principles,the sequence stratigraphic framework is established. Researcharea has been recognized out7sequence boundaries,bottom up respectively:the bottom of theDenglouku group(SB1),the bottom of the second member of the Denglouku group(SB2), thebottom of the third member of the Denglouku group(SB3),the bottom of the fourth member ofthe Denglouku group(SB4),the bottom of the Quantou group(SB5),the bottom of the secondmember of the Quantou group (SB6),the top of the second member of the Quantougroup(SB7).SB1,SB5and SB7are the boundaries of the boundaries of the super-sequence.Each sequence can be diveded into system domain.By analyzing the stratum thickness map and T0map,the formation thickness distributioncharacteristics are analyzed,and the sequence interface structural characteristics arestudied.The types of traps include anticline,faulted anticlines and faulted block trap in thestudy area.Through the analysis of single well phases and multi-well phases,the study area isidentified to5kinds of facies,22kinds of subphase,38species of micro-phase;in addition forthe characteristic of the study area, the7three-level sequence of sedimentary microfaciesdiagram of Denglouku Group-Members2of the Quantou have been described out,depositional evolution sequence of Denglouku Group-Members2of the Quantou have beensummed up.According to the source-reservoir-cap combination,Denglouku Group-Members2of theQuantou formation is divided into three sets of reservoir-cap,the paper analyzes the favorableexploration areas in this area.更多还原
