| 摘 要： | 采用长管模型驱油试验和平板模型驱油试验研究了调剖时机对原油采收率的影响 .结果表明 ,在油井见水时就在对应的注水井采取措施进行调剖 ,可减缓地层不均质性的加剧程度 ,更有效地发挥调剖剂的封堵效果 ;在综合含水高达 80 %以上后进行调剖 ,尽管也能提高原油采收率 ,但采收率提高的幅度则较小 .因此 ,调剖宜早进行

| Abstract: | The effect of profile control time on oil recovery efficiency is studied by tubular and planar models. The results show that the profile control of injection wells should be carried out as soon as water breakthrough appears in oil wells, which may reduce the deteriorating rate of formation heterogeneity and increase the water plugging result of profile control agent. When water cut reaches above 80%, even if the measures of profile control is taken, the increase of oil recovery efficiency is less than that when profile control is carried out earlier. |
