摘要： CO2 泡沫调堵是一种选择性化学调剖堵水方法, 其应用技术的关键在于发泡剂的选择。针对油藏高温、高矿化度特殊环境,综合考虑了影响发泡剂性能的关键因素,并以此为基础筛选出了具有良好抗盐、耐温性能及 pH 值稳定性的表面活性剂 YFP-2 作为发泡剂。借助岩心驱替流动实验,进一步研究了该发泡剂在模拟油藏环境下所产生的泡沫对驱替岩心的封堵作用。封堵实验结果表明,该泡沫体系具有较强的流动阻力保持性能,且对驱替剂的流动具有一定的转向作用。

Abstract: CO2 foam profile/water plugging technique is a selective chemical method, the key point of which is the selection of foaming agent. In view of the particular reservoir with high temperature and high salinity, a comprehensive survey of critical factors affecting the foaming agent behaviors is conducted, by which the surfactant YFP-2 with good salt resistance, temperature tolerance and pH stability is selected as the main foaming agent. Also, this paper studies the sealing effect of this foaming agent on the displaced cores under the environment of analog reservoir by means of core flow test. The result shows that this CO2 foam system has stronger flow resistance holding capacity and function to change flow direction in the rock.

Key words: high temperature, high salinity, CO2, foam, foaming agent, water plugging
