【摘要】 利用现有岩芯资料、测井资料和地震资料,对沉积相标志进行综合研究,认为登娄库组沉积属于三角洲沉积体系,亚相类型属于三角洲平原亚相,主要发育分支河道、分支河道间、天然堤、决口扇共四种微相,其中分支河道广泛发育,是最重要的储层微相类型。更多还原

【Abstract】 This article mainly consults existing core,logging,seismic data and previous research results.Through comprehensive research of sedimentrary facies marks,Denglouku Formation is thought as delta sedimentary system.The type of subfacie is delta plain facie,and developes four microfacies such as branch channel,inter-channel,natural levee and crevasse splay.And branch channel develops widely.It is the most important type of sedimentary microfacies.更多还原
