摘　　要：随着中国油田的不断开发,陆续出现许多高温高盐油藏,苛刻的油藏环境对于调剖剂的要求越来越高。通过浊度仪、界面张力仪、乌式黏度计、微孔滤膜过滤实验和砂管封堵实验对新型调驱剂磺甲基酚醛树脂(SPFR/AP-P4)体系的分散稳定性、界面性能、黏度及封堵性能进行研究。经研究发现在分散体系磺甲基酚醛树脂质量浓度为1 000 mg·L^(-1)、Na Cl质量分数为1.5×10^(5) mg·kg^(-1)时,随着AP-P4质量分数的增加,体系稳定性增强、界面张力下降、黏度增大、封堵能力增强。因此,SPFR/AP-P4体系和磺甲基酚醛树脂聚集体体系相比,具有良好的分散稳定性、封堵能力和运移能力,是一种性能良好的新型耐盐调剖剂。With the continuous development of oil fields in China,many high-temperature and high-salt reservoirs have appeared one after another,and the harsh reservoir environment requires more and more profile control agents.In this paper,The dispersion stability,interface properties,viscosity and plugging properties of SPFR/AP-P4 system were studied by turbidimeter,interfacial tensimeter,viscosimeter,microporous membrane filtration test and sand tube plugging test.It was found that,when the mass concentration of sulfomethyl phenolic resin in the dispersion system was 1000 mg·L^(-1) and the mass fraction of NaCl was 1.5×10^(5) mg·kg^(-1),with the increase of AP-P4 concentrationmass fraction,the stability of the system increased,the interfacial tension decreased,the viscosity increased,and the plugging ability increased.Therefore,SPFR/AP-P4 system is a new salt-resistant profile control agent with good dispersion stability,plugging ability and migration ability.
