摘　　要：针对特高含水油田高温高矿化度的地质情况选择了一种具有耐温耐盐性的堵水剂进行研究,通过研究p H值、温度、矿化度和交联剂浓度等参数对于成胶时间、成胶强度等交联性能的影响,对该堵剂配方做进一步优化并研究其适应性。结果表明,该堵剂能够用于特高含水期的高温高矿化度油井进行堵水。For oil fields with geological conditions of high water cut, high temperature and high salinity, a plugging agent with heat resistance salt resistance was chosen to carry out water plugging experiments. Effects of p H, temperature, salinity, cross-linking agent concentration and other parameters on the crosslinking performance including gelling time and gel strength were investigated to optimize the blocking agent formula, and its adaptability was studied. The results show that the plugging agent can be used for water plugging of the high temperature and high salinity oil well.
