| 摘 要： | 针对吉林油田黑79区块CO_2气窜的问题,提出用CO_2泡沫封堵气窜。利用高温高压泡沫工作液性能测试装置评价CO_2泡沫体系的性能,探讨温度、矿化度和含油饱和度对CO_2泡沫体系性能的影响;通过分流实验,研究CO_2泡沫改善剖面的情况。结果表明:随着温度的升高,CO_2泡沫半衰期和综合指数先上升后下降;随着矿化度的增加,半衰期和综合指数先增大后减小,矿化度对泡沫高度影响较小;随着含油饱和度的增加,泡沫高度、半衰期和综合指数均减小;泡沫可以有效启动低渗填砂管,低渗填砂管提高采收率幅度优于高渗填砂管。该项研究为吉林油田黑79区块控制气窜提供了参考依据,有助于进一步完善泡沫体系控制气窜理论。
