摘　　要：本文结合南海东部典型强水驱海相砂岩油田—XX油田开发现状及难点,提出同时考虑PLT产出剖面拟合及时移测井饱和度拟合的多维拟合技术,循环校正油藏数值模型,精准定位剩余油富集区,提出调整井潜力井位,将极限井距降低至100m,实施后效果良好,潜力得到了实际验证,有效提高了油田采收率。Based on the development status and difficulties of XX Oilfield,a typical strong water drive marine sandstone oilfield in the eastern South China Sea,this paper puts forward a multi-dimensional fitting technology that considers PLT production profile fitting and time-lapse logging saturation fitting at the same time,cyclically corrects the reservoir numerical model,accurately locates the remaining-oil enrichment area,and proposes to adjust the potential well position,reducing the limit well spacing to 100m m.After implementation,the effect is good,the potential has been verified in practice,and the oil recovery rate of the oilfield has been effectively improved.
