摘　　要：针对不同含水阶段下剩余油变化规律不明及流场描述难度大的问题,通过制作三维人造岩心确定高含水油藏流场演变过程主控因素。结果表明:透率极差、油水黏度比、注入速度对于优势渗流场形成时机的影响较大;优势渗流场以水驱特征曲线上翘为优势渗流通道(低效循环区)形成时机的判别依据。研究成果为高含水油藏流场分布和流场调整起到了指导作用。In response to the problem of unclear remaining oil variation patterns and difficult flow field description at different water cut stages,the main controlling factors of the flow field evolution process in High water cut reservoirs were determined by making three-dimensional artificial rock cores.The results indicate that the extremely poor permeability,oilwater viscosity ratio,and injection speed Have a significant impact on the timing of the formation of the dominant seepage field;The dominant seepage field is determined by the upward curve of the water drive characteristic curve as the timing for the formation of the dominant seepage channel(low efficiency circulation zone).The research results Have provided guidance for the distribution and adjustment of flow fields in High water cut reservoirs.
