AM/AOPS/DEDAAC共聚物防塌降滤失剂的合成

Synthesis of the AM/AOPS/DEDAAC Copolymer Anti-sloughing Filtrate Reducer

采用氧化—还原引发体系合成了丙烯酰胺/2-丙烯酰氧基-2-甲基丙基磺酸/二乙基二烯丙基氯化铵三元共聚物。初步评价了共聚物的钻井液性能。结果表明,AM/AOPS/DEDAAC共聚物具有较好的耐温抗盐能力。

The acrylamide ,2 -acryamidoxygen- 2 -methylpropanesulfonic acid and diethyl diallyl ammonium chloride（ AM/AOPS/DEDAAC ）copolymer filtrate reducer is synthesized by redox initial system. The mud properties of the AM/AOPS/DEDAAC copolymer is evaluated in laboratory. The experimental results show that the AM/AOPS/DEDAAC copolymer has very good capacites of depressing the filter loss, heat resistance and salt tolerance when used as drilling fluid filtrate reducer.
