页岩抑制剂的研制与评价

Preparation and Evaluation of a Shale Inhibitor

以丙烯酰胺(AM)为主单体,与阳离子单体二甲基二烯丙基氯化铵(DMDAAC)及2-甲基-2-丙烯酰胺基丙磺酸(AMPS)和丙烯酸钾(AA)进行四元水溶液聚合,合成了一种页岩抑制剂,并对其性能进行了评价。结果表明,试验所合成的产物具有较强的抑制能力和降失水能力,此外,还具有一定的耐温性和耐盐性,是一种集抑制性和降失水性为一体的两性离子聚合物。

The synthesis conditions was prepared with AM,AMPS,DMDAAC and AA as materials.The results indicate that the product with certain molecular references is well with the ability of inhibition and fluid loss control,additionally,with the anti-salt and anti-high temperature,and the product is a kind of amphiprotic polymer with both inhibition ability and fluid loss control in fact.
