摘　　要：针对凝胶调剖剂用于封堵高温高盐油藏时需要满足耐温抗盐要求,综述了近年来国内外凝胶调剖剂的研究进展;探讨了聚合物类、生物类、木质素磺酸盐类、膨胀型颗粒类、泡沫类等凝胶调剖剂的作用机理、配方和性能;指出了凝胶调剖技术存在的不足及发展趋势,即现有的凝胶调剖剂未能很好地满足高温高盐等复杂油藏的实际需求,特别是蒸汽驱过程中汽窜现象导致的驱替波及体积小、采出程度低、油藏动用程度差、边底水锥进等问题还未得到实质性的解决,今后凝胶调剖剂主要朝着耐高温、抗高盐、环保廉价等方向发展。Gel must meet the requirements of temperature resistance and salinity tolerance when it is used as a profile agent to seal the high temperature and high salinity reservoir. In this paper, research progress of gel plugging agents was reviewed. The mechanism, formulation and performance of different gel plugging agents were discussed, such as polymer-type, biology-type, lignosulfonate-type, inflating particle-type and foam-type. The shortage and development trend of gel profile control technology have been pointed out, namely the existing gel plugging agents can not completely meet the requirements of complex reservoirs of high temperature or high salinity, and particularly the issues of small swept volume, low level of recovery, poor degree of reservoir utilization and edge-bottom water coning caused by steam channeling in steam flooding are still not solved. Therefore, higher temperature resistance and salinity tolerance, more environmental friendly and less expensive gel plugging agents are the development trend in the future.
