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、NaCl质量分数为1.5×105 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.
Abstract
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.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 1 000 mg·L-1 and the mass fraction of NaCl was 1.5×105 mg·kg-1,with the increase of AP-P4 mass 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.
