【摘要】 在准噶尔盆地西北缘车排子地区侏罗系扇三角洲沉积体系岩石相、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。同时还对该区扇三角洲沉积模式和岩性圈闭形成条件进行了分析。研究结果对该区隐蔽油气藏的勘探具有一定的指导意义。更多还原

【Abstract】 This paper studies the petrographic facies, electrofacies and seismic facies of the Jurassic fan delta system in Chepaizi area, northwest margin of Junggar basin, and classifies sedimentary microfacies. The study indicates that this fan delta system is characterized by near-source, coarse grain, high accumulation rate, and various petrographic and seismic facies. The sedimentary pattern and forming conditions of lithologic traps in the fan delta are analyzed. The result of this study may guide subtle reservoir exploration in this area.更多还原
