摘　　要：周矶油田因平面及纵向非均质性强,制约了注采调整,影响了开发效果。以该区块周16、周21为研究对象,通过系统分析,认为调整困难的原因主要是平面非均质性严重,注水单向突进,以及部分井区层间差异大,合采时薄差层不出力等,可采用油井转注、动态调水等方法改变油藏的水驱方向,提高采收率,结合剩余油研究,重建注采井网,挖潜层间剩余油,有效提高地质储量动用程度。Due to the strong plane and longitudinal heterogeneity in Zhouji Oilfield,the injection-production adjustment is restricted and the development effect is affected.Through systematic analysis of Zhou 16 and Zhou 21 in this block as the research objects,it is concluded that the main reasons for the adjustment difficulties are serious plane heterogeneity,one-way water injection inrush,large inter-layer differences in some well areas and no output of poor thin layers while combining production.Methods such as oil well transferred to water injection well and dynamic water transfer can be used to change the reservoir waterflood direction and improve oil recovery.Based on the research of remaining oil,the injection-production well network is reconstructed to dig the remaining oil between subsurface layers and effectively improve the utilization degree of geological reserves.
