摘要/Abstract

摘要： 基于所建立的可模拟水驱优势通道发育的三维物理模型，结合核磁共振，对不同封堵优势通道方法下剩余油宏观分布变化及微观孔隙动用进行了研究，明确了优势通道下剩余油动用内在控制机制，并利用数值模拟，对优势通道下剩余油动用适应性及策略进行了总结。结果表明：通过量化核磁成像图片与流体饱和度关系，可对三维模型进行无探针饱和度监测；考虑封堵效率，短半径高强度调剖与中长半径调驱分别适合于弱与强优势通道，且初始潜力分布对封堵效果有重要影响；大孔隙中剩余油动用对整体提高采收率贡献最大，其也是造成不同封堵方式剩余油动用差异的主要因素，且由于弱优势通道模型各孔隙窜流程度及初始潜力分布较均匀，其中小孔隙动用略好于强通道模型；弱优势通道储层的堵剂溶度不宜过高，以保证其注入性，而强优势通道储层需要较高堵剂注入PV数，以达到封堵目的。该研究对高含水油田调剖堵水决策与优化设计有一定理论指导意义。

Abstract: Based on 3D physical model which can simulate growth of dominant flowing path and nuclear magnetic resonance(NMR),macro remaining oil distribution and production contribution from micro pore under different plugging methods are studied.Furthermore,controlling mechanisms of remaining oil production in dominant flowing path are summarized.Finally,strategy of remaining oil production and its adaptability are obtained through numerical simulation.The results show that,by establishing the correlation between NMR imaging and oil saturation,oil distribution in 3D model can be monitored without probes.Considering the plugging efficiency,short and deep profile controls can be applied to weak and strong dominant flowing paths respectively,and initial potential has the most important influence on the plugging.Remaining oil production in large pore contributes to most part of the overall plugging.It is also the main factor causing different recovery improvement among different plugging methods.Because channeling and initial potential in different kinds of pores are more uniform in weak path model,production of medium and small pores is slightly more efficient than in a strong model.Plugging agent content for weak path should not be too high in order to guarantee injection,and to achieve plugging objective,strong path needs relatively high injection pore volume.This study can provide some theoretical guidance for plugging design and optimization of high water cut oilfiled.
