| 摘 要： | 为了揭示歧口凹陷古近系岩性地层油气藏分布规律并指导钻探,应用层序地层学理论,结合三维地震、测井和岩心资料对岐口凹陷滨海地区古近系开展了层序地层分析。古近系作为一个超层序组发育3个超层序、11个三级层序。根据同沉积构造坡折类型,可以把层序划分为挠曲坡折型层序和断坡型层序2种层序类型。其中:断坡型层序主要发育在超层序1,挠曲坡折型层序主要发育在超层序2和超层序3。在滨海斜坡区,超层序2和超层序3由挠曲坡折控制的层序低位体系域和高位体系域砂体与湖扩展体系域优质烃源岩配置良好、埋深适中、成藏条件优越,是地层岩性油气藏发育有利区。提出了模型正演和有效数计算相结合的地震属性优选方法及地震属性控制下的储层预测技术,并利用该项技术在有利区内预测了6个有利目标。

| Abstract: | In order to reveal and display the distribution law of the Paleogene stratigraphic-lithological reservoir of Qikou sag and provide guidance toward the drilling,this paper has utilized the sequence stratigraphy theory with the integration of 3D seismic data,well log data as well as core data to set the work of sequence stratigraphy analysis of it into motion.Paleogene,as a super sequence series,has developed three super sequences and 11 three-order sequences.According to the pattern of sedimentary structure ... |
