大庆长垣扶余油层沉积层序构成及充填响应
|
摘要
大庆长垣是松辽盆地北部最重要的含油气构造,扶余油层是其主要含油层位之一。根据岩心、测井和高分辨率地震等基础地质资料,将扶余油层划分为2个三级层序、7个四级层序。其储层砂体为冲积-河流环境的网状河道和曲流河道沉积,砂体厚度横向变化快,河道砂体不易预测和识别。在沉积演化上,河道发育经历了曲流河道—网状河道—分支河道的变化过程;决口扇在F2.2—F1.3时面积扩张,随着湖侵加剧,决口扇范围缩小至消亡;洪泛平原也随着基准面的上升、湖泊的发展,颜色由红色逐渐过渡到灰绿色和灰白色,分布面积也逐步缩小;湖相由早期的孤立河间湖发展到后期连片分布的稳定湖。层序构成和沉积响应过程受松辽盆地裂后热沉降构造背景控制,同时受气候和物源条件的双重影响。
Daqing Placanticline is the most important oil-gas structure in the Songliao basin,and the Fuyu oil layer is one of the main oil-bearing formations.On the basis of well drilling,well logging and high reflection seismic data and so on,Fuyu oil layer can be divided into two third-order sequences and seven fourth-order sequences.Its reservoir sand body is anastomosing river channel and meandering river channel deposit under fluvial-river environment,sand body thickness varies fast horizontally.The channel sand body is hard to predict and identify.As for sedimentary evolution,the evolutionary process of the river channel is meandering channel-anastomosing channel-distributary channel;Crevasse-splays expand from F2.2 to F1.3,and contract even to vanish along with the transgressive development;The color of floodplains changes gradually from red to sage green and gray and the distribution area contracts during the base level ascending and lakes developing.Lacustrine develops from the early isolated lake among rivers to the later stable lake all over the whole study area.Sequence architecture and sedimentary response are controlled by the tectonic background of thermal subsidence in the Songliao basin,in addition,influenced by climate and provenance.
