阴离子表面活性剂 【理化性能】 对淡水泥浆、盐水泥浆、饱和盐水泥浆均有良好的降失水性，作用效果随加入量的增加而提高。具有高温抗盐性。

【技术指标】 【用 途】 此共聚物降失水剂具有抗温抗盐和协同增粘作用，作为固井液 In view of the present domestic use cement filtrate reducer common salt, ability of resisting high temperature difference problem, acrylamide (AM), N, N two methyl acrylamide ( DMAM ), 2 - acrylamide - 2 - methyl methacrylate ( AMPS ) as raw material to synthesize new filtrate reducer for oil well cement, the fresh water, saline and high density cement slurry system performance was evaluated, the evaluation results indicate that, the polymer at a temperature of 90 DEG C can be fresh water mud fluid loss control in 50mL left and right sides, the slurry water loss also has strong control function, and the filtrate reducer for cement slurry system can keep the temperature of 150 DEG C it has low filtration loss, in high density cement slurry system also showed high stability and compatibility.
