中文摘要:
      针对单一驱油泡沫体系稳定性差,驱油效果的差的问题,进行了强化泡沫驱室内评价实验,在模拟储层温度的恒温条件下,将聚合物溶液与不同种类的起泡剂进行配制,通过评价初始起泡高度和半衰期两个关键指标,确定甜菜碱加十二醇复配体系作为起泡剂。并通过不同起泡剂浓度敏感性分析,优选质量浓度为0.3%的甜菜碱复配0.04%的十二醇为最佳体系。通过将强化泡沫体系应用到海上聚合物驱油田,试验区块生产形势明显好转,能够为海上同类油田优选泡沫体系起到借鉴作用。
英文摘要:
      In order to solve the problems of the poor stability and the poor oil flooding efficiency of the single foam flooding system. Laboratory evaluation experiment of enhanced foam flooding was carried out. Under the constant temperature condition of simulated reservoir temperature, the polymer solution was prepared with different kinds of foaming agents, by evaluating the initial foaming height and half-life, betaine and dodecanol compound system was determinate as the foaming agent. Through the sensitivity analysis of different foaming agent concentration, the optimum system was composed of 0.3% betaine and 0.04% dodecanol. By applying the enhanced foam system to offshore polymer flooding oilfield, the production performance of the tested field has obviously improved. It can serve as a reference for optimizing foam system for similar offshore oilfields.
