| 摘 要： | 为考查深部调剖剂YG型聚合物微球在中原油田高温高矿化度油藏中的性能,通过透射电镜显微照相、吸水膨胀实验、岩心驱替实验和现场先导试验对其进行了性能评价与矿场应用。性能评价结果表明：该聚合物微球体积微小,可均匀分散在溶液中,与地层水表现出良好的配伍性;在95℃文留油田回注污水中,吸水膨胀倍数达40倍以上,具有较好的耐温抗盐和吸水膨胀性能;向中、低渗透率岩心注入微球体系过程中,呈现开始压力迅速上升、然后趋于稳定、压力略有下降的波动过程,具有较好的注入性;向中、高渗透率岩心注入微球体系过程中,随溶胀时间的延长,封堵率逐步增加,第10天达到最大,为17.14%。采用YG型微球在文留油田文10东块进行了深部调剖先导试验,取得了较好的开发效果。图6表4参5
