松辽盆地南部扶余油田泉头组四段沉积相研究

以岩心和测井分析资料为基础,通过对松辽盆地南部扶余油田泉头组四段的泥岩颜色、粒度分布、沉积构造以及生物化石、岩石类型及其组合等的研究,确认该工区泉头组四段为浅水三角洲相沉积。将其进一步划分为三角洲平原和三角洲前缘两个沉积亚相,绘制了扶余油田沉积微相平面展布图,据此建立了扶余油田沉积模式,研究了它的沉积演化特征,为老油区的挖潜上产提供了依据。

Sedimentary facies of the fourth member of the Quantou Formation in Fuyu oilfield, the South Songliao Basin

Based on the core and logging datum,and through the research of mudstone's colors,granularity distribution,sedimentary structures,fossils,rock types and their association in the fourth Member of the Quantou Formation in Fuyu oilfield in south part of Songliao basin,it confirmed that the sedimentary environment here was shallow delta facies.Furthermore,it was classified two subfacies of delta plain and delta front.The plan distribution map of sedimentary microfacies of Fuyu oilfield was draw,and based on it,the sedimentary model of Fuyu oilfield was established and the evolutionary characters were also studied.All of those offer basis for increasing reservoir in old oilfields.
