| 摘 要： | 针对双河油田特高含水开发后期的地质及剩余油分布特点．优选出了适用于60～90℃油藏的深度调剖剂，该调剖剂可用现场新鲜污水配制，具有成胶时间长、交联强度适中、可封堵又可运移、热稳定性好的特点。同时应用井间示踪技术识别了试验区的大孔道发育和剩余油分布情况，应用数值模拟技术对5口井的深度调剖方案进行了优化。优化的调剖方案实施后，初步显示出油层中的大孔道得到封堵，对应油井见到了一定的增油降水效果。

| Abstract: | Based on the geological characteristics and the residual oil distribution of Henan Oilfield during the super-high water cut stage, the reagent suitable for reservoirs of 60-90 centigrade was presented with the characteristics of long gelatinize time, moderate cross-link intensity, plugging and transportation, good thermal stability. In addition, large channels identification and residual oil distribution in test area were studied by means of the tracer technique. Profile control schemes of 5 wells were optimized by means of numerical simulation. Field applications show that the large channels in the formations are sealed off and the oil recovery is increased, meanwhile, the water production is decreased. |
