在双层地质模型上进行了凝胶处理数值模拟研究。模型层与层间水平方向渗透率之比的变化范围为0．0033～0．5，各层垂向／水平渗透率之比相同，变化范围为0．001～0．1。凝胶注入下部高渗透层，后续聚合物驱／水驱进入各层液量取决于其流度值。研究结果表明，在低于kV／kH比情况下，近井地带凝胶处理可以提高采收率，反之，调剖效果较差，甚至无效。
The numerical simulation of gel treatment was carried out on double-layered geological model. The ratio of horizontal to horizontal permeability of the model layer varies from 0.0033 to 0.5, with the same ratio of vertical to horizontal permeability in each layer, ranging from 0.001 to 0.1. The gel is injected into the lower high permeation zone, and the amount of liquid entering the subsequent polymer flooding / flooding depends on its flow value. The results show that near-wellbore gel treatment can increase oil recovery below the kV / kH ratio, whereas the profile control effect is poor or ineffective.
