摘　　要：王集油田位于泌阳凹陷北部斜坡带的东北部,是一个岩性和断层共同作用的复杂油气藏。开发后期由于对储层和地下油水关系认识不清,注水和剩余油挖潜效果不佳。鉴于沉积相对储层和油气运聚的控制作用,重点分析了本区取心井的岩性、粒度、岩石相与测井相特征,并进一步从平面上和剖面上研究了沉积微相的空间展布,对油藏精细地质建模和剩余油挖潜方案调整有重要的指导意义。Wangji Oilfield,a complex reservoir dominated by lithology and faults,is located at North-east part of northern slope in Beiyang depression.At later stage of oilfield development,water injection and remaining oil development is inefficient,lacking of cognition of reservoir and water-oil relation.Considering that sedimentary fatties has a control effect to reservoir and fluid movement,this paper makes analysis of sedimentary characteristics of corning wells including lithology,grain size,reservoir petrology and log feature,then carries out studies on distribution of sedimentary microfacies from the plane and profile,which has an important leading meaning to fine geological modeling and development adjustment of remaining oil.
