摘要
针对聚合物驱后堵水调剖技术试验区选择的困惑,运用油藏数值模拟的技术手段,从储层非均质性的角度,对试验的选区原则进行研究,探索了聚合物驱后堵水调剖试验区选择的适应性条件,初步确定聚合物驱后油藏堵水调剖试验区选区原则为:高渗透条带渗透率大于等于3000×10-3μm2,渗透率级差大于等于3。
In view of the puzzlement to water-plugging and profile control pilot area selecting after polymer flooding,from the aspect of formation heterogeneity,reservoir simulation technology was used to study the experimental block choosing rules,the conformability condition of experimental block after polymer flooding was investigated.The preliminary rules of water-plugging and profile control after polymer flooding are that the permeability of high permeable belt is not less than 3000×10-3 μ m 2,and the permeability differential is not less than 3.
