探讨了高温高盐油藏对堵剂性能的要求以及常规堵剂耐温抗盐堵剂改性的途径,综述了近年来国内对耐温抗盐堵剂的室内研究进展和矿场应用情况,包括聚合物凝胶、体膨颗粒、盐沉析技术、聚合物微球等适合高温高盐油藏的调堵技术,并指出了在堵剂的研究与应用中存在的一些问题。表1参42
In this paper, the requirements of chemical water plugging in high temperature and high salt reservoir and the modified method of the ordinary plugging agents were probed, and the research advances and the field application of the high temperature resistant and high salinity tolerant plugging agents was reviewed, including polymer gel, preformed gel particles, salt precipitation and polymer microsphere, which are appropriate for high temperature and high salinity reservoir. In addition, the problems still existing in research and application were mentioned.
