影响低度交联AMPS共聚物驱油体系性能因素的探讨

Effects on the Behavior of Low Crosslinked AMPS Copolymer Oil Displacement System

探讨了影响2-丙烯酰胺基-2-甲基丙磺酸(AMPS)共聚物交联体系热稳定性和凝胶时间的各种因素。实验结果表明,AMPS共聚物交联体系的热稳定性主要由聚合物分子结构和交联剂种类决定,同时也受到温度的影响;AMPS共聚物交联体系的凝胶时间受温度和pH值因素影响明显。

The effects on the behavior (including thermal stability and gelling time) of low crosslinked AMPS copolymer oil displacement system are examined. The result shows that the thermal stability of AMPS copolymer mainly depends on the polymer structure and the kinds of the crosslinkers, and gelling time of the AMPS is sensitive to temperature and pH.
