摘要: 针对低渗透油田开发过程中存在的注水困难、水淹程度高、注入水利用效率较低以及注气开采易发生气窜的问题,通过大量的室内物理模拟实验与测试,为吉林油田某低渗透区块CO2 泡沫驱优选出最佳的CO2 泡沫体系,并对体系的稳定性、发泡性、可注入性及渗透率适用范围等进行了特性评价。研究结果表明,三种发泡剂均
具有良好的发泡性能和稳定性,且均在可注入的范围内;当温度从45℃升到100℃时,泡沫体系的半衰期急剧减小,稳定性能均变差;三种泡沫体系中FP388发泡性最好,综合性能最优。

Abstract: There are many problems in the development process of the low permeability oilfields including water injection difficulty, high water flooded degree, low utilization efficiency of injected water and gas channeling of gas injection. Through a large number of laboratory physical simulation experiments and tests, the best CO2foam system was selected out for a low permeability blocks CO2foam flooding in Jilin oil field. The stability, foaminess, injectivity and applicable scope of the permeability of three systems were conducted. The results showed that the three kinds of foam agent all had good foaminess and stability, and all of them could be injected within the range. When the temperature rose from 45 ℃ to 100 ℃, the halflife of foam systems sharply reduced, and the stability of them turned bad. In the three foam systems, FP388 was the optimal one which had best foaminess and comprehensive performance.
