大港孔店南部王官屯地区孔三段扇三角洲沉积特征及典型相序
|
摘要
在黄骅坳陷孔店南部王官屯地区孔三段扇三角洲沉积体系岩性相、测井相、地震相分析研究基础上,对该区扇三角洲沉积体系进行了沉积微相组合划分,并对各沉积相组合特征分析。研究认为,该区扇三角洲沉积的总体特征为:近源、粒级粗、堆积速率快,岩石相、地震相类型丰富。同时还建立了该区扇三角洲相的典型相序。研究结果对该区隐蔽油气藏的勘探具有一定的指导意义。
Based on analyzing the petrographic facies, electrofacies and seismic facies of the fan delta system of Kong3 member in Wangguantun area,north of Kongdian,Huanghua depression,the paper classifies sedimentary microfacies,and analyzes assemblage characteristics of sedimentary facies.The study indicates that this fan delta system is characterized by near-source,coarse grain,high accumulation rate,and various petrographic and seismic facies.And the paper establishes the typical face sequence of the fan delta of this area.The research results have a very important guiding significance for deepening the oil and gas exploration in this area.
