松辽盆地北部上白垩统四方台组河流相层序沉积特征
|
摘要
通过岩心观察与测井解释,应用沉积学和层序地层学原理和方法,对松辽盆地北部四方台组河流相沉积特征与层序地层特征进行了研究。结果认为:四方台组主要发育辫状河和曲流河相,以曲流河相为主;辫状河主要发育河床滞留沉积、心滩与河漫滩微相,曲流河主要发育河床滞留沉积、边滩、河漫滩、河漫湖泊与决口扇微相;四方台组可划分为2个三级层序(SQ1、SQ2)、8个四级层序(体系域),其中低水位体系域(LST)主要发育辫状河心滩,水进体系域(TST)和水退体系域(RST)主要发育曲流河边滩、河漫滩,高水位体系域(HST)主要发育曲流河决口扇、河漫湖泊。该成果为后期四方台组石油地质与矿床地质研究奠定了基础。
With the help of the core observation and logging interpretation,and moreover by means of the principles and methods of sedimentology and sequence stratigraphy,the fluvial sedimentary characteristics and sequence stratigraphic features of Sifangtai Formation in North Songliao Basin were studied. The achievements show that the braided river and meandering river facies are mainly developed in Sifangtai Formation,among which the meandering river facies is the principal facies; the microfacies such as the channel lag,channel bar and floodplain are the key developed forms in the braided river facies,the channel lag,point bar,floodplain,flood-pond and crevasse splay microfacies are mainly developed in the meandering river; Sifangtai Formation can be divided into 2 three-level se-quences( SQ1 and SQ2) and 8 four-level sequences( system tract) : the braided channel bar is mainly developed in the lowstand system tract( LST),the meandering-river point bar and floodplain are generally developed in the transgressive system tract( TST) and regressive system tract( RST),the meandering-river crevasse splay and floodpond are mainly developed in the highstand system tract( HST). The achievements have laid the basement for the researches on the petroleum geology and mineral deposit geology of Sifangtai Formation in the future.
