High Temperature Salt Resistant Filter Loss Reducers for Water Base Drilling Fluids: Synthesis with Explosive Polymerization Method and Performance Evaluation

  • 摘要: 为了克服水相聚合法产物含量低、烘干过程分子量易增大和高能耗等问题,通过爆聚法利用单体苯乙烯磺酸钠和2-丙烯酰胺-2-甲基丙磺酸分别与丙烯酰胺和二甲基二烯丙基氯化铵合成制备了抗高温抗盐降滤失剂WS-1和WS-2。借助红外光谱(FT-IR)和热重分析(TGA),表征了降滤失剂的分子结构和热稳定性,并且进行了降滤失剂在高温高盐水基钻井液中的流变性和高温高压滤失性能的影响实验。结果表明,具有刚性苯乙烯磺酸钠分子链段的降滤失剂WS-2具有良好的高温稳定性,热分解温度为310℃,降滤失剂WS-2在220℃饱和盐水基钻井液中高温高压滤失量为7.6 mL;具有大分子支链2-丙烯酰胺-2-甲基丙磺酸链段的降滤失剂WS-1热分解温度为270℃,200℃饱和盐水基钻井液中高温高压滤失量为1.6 mL;利用爆聚法合成的降滤失剂WS-1和WS-2均具有良好的抗温抗盐性能。
