摘要

系统研究了扶余油层沉积特征、沉积微相及沉积演化。结果表明,松辽盆地南部泉四段沉积时期,盆地基底稳定缓慢沉降,地形平缓,在湖盆扩张及浅水背景下,河流入湖形成大型浅水湖泊三角洲沉积相,分为三角洲平原和三角洲前缘两个亚相。前者包括分支河道、天然堤、决口扇、分支河道间湾微相,后者包括水下分支河道、水下天然堤、水下分支河道间湾、河口坝与远砂坝。在较强的水动力及整体水进背景下,形成了枝状浅水三角洲沉积模式。

Abstract

Based on the systematic study of the sedimentary characteristics, sedimentary, micro-facies, and sedimentary evolution of Fuyu reservoir, the following conclusions are obtained. During the deposition of the 4th member of the Quantou formation in southern Songliao basin, the basement sinks stably and slowly, the terrain is gentle and smooth slope. Under the background of lake basin expansion and shallow, river flees into the lake, forms a large shallow lake delta deposition, and divides into two sub-phases, namely, delta plain and delta front. The former delta facies include branch channel, nature levee, crevasse splay, and inter branch channel; the later delta facies include subaqueous distributary channel, subsea natural levee, sub-sea inter branch channel, mouth bar, and distal bar. The shallow delta sedimentary model forms as the result of strong hydrodynamic and the fast water invasion. The direction of the remainder oil is pointed out, and the adjustment for developing project with guiding significance is provided.
