Synthesis and Properties of a High Temperature Calcium and Salt Resistant Quinary Copolymer Filter Loss Reducer

  • 摘要: 针对深部地层钻井过程中遇到的高温、高矿化度等问题,以AM、AMPS、DMDAAC、DMAM、SAS为聚合单体,采用氧化-还原引发体系进行水溶液共聚,合成了一种五元共聚物降滤失剂。通过优化实验确定最佳合成条件,采用红外光谱和热重分析进行表征,并评价其在钻井液基浆中的性能。实验结果表明,合成的五元共聚物抗温达180℃、抗盐至饱和、抗钙达1.25%;五元共聚物加量为2%时,淡水、饱和盐水及含1.25% CaCl2的基浆经180℃老化16 h后的滤失量分别为6.4、15.6和7.2 mL,均为加2% Driscal的不同基浆滤失量的50%左右。
