    摘要:

    摘要:利用三维网络模型模拟了饱和油、水驱和聚驱三个驱替过程,研究了聚驱后的微观剩余油分布状态,分析了孔隙半径、配位数、形状因子、润湿性等孔隙结构参数对聚驱后剩余油分布的影响。结果表明:随着孔隙半径、配位数、形状因子的增大,聚驱后剩余油百分含量降低;水湿油层的聚驱采收率高于油湿油层的聚驱采收率。 关键词:网络模型;聚合物驱;剩余油;微观分布

    Abstract:

    Abstract: Using the three-dimensional network model, the saturating oil, water flooding and polymer flooding processes are simulated and the residual oil distribution pattern is studied in this paper. The influences of pore size, coordination number, shape factor and wettability on the residual oil distribution are analyzed. The results show that: With the increasing of the pore size, coordination number and shape factor, the residual oil after polymer flooding decrease; the oil recovery of water wet reservoir is higher than that of oil wet reservoir. Key words: network model; polymer flooding; residual oil; microscopic distribution
