钻井液降滤失剂PAMS601的合成与性能

Synthesis and Properties of PAMS_(601) Filtrate Reducer for Drilling Fluid.

摘要: 采用氧化－还原引发体系合成了２－丙烯酰胺基－２－甲基丙磺酸（ＡＭＰＳ）－丙烯酰胺ＡＭ）二元共聚物钻井液降滤失剂ＰＡＭＳ６０１，借助红外光谱和ＤＴＡ－ＴＧ研究了共聚物的结构和热稳定性，并对其泥浆性能进行了室内评价。结果表明，本文合成的ＰＡＭＳ６０１降滤失剂热稳定性好，降滤失能力和抗浊抗盐能力强。

Abstract: The acrylamide and 2-acrylamido-2-methylpropanesulfonic acid copolymer filtrate reducer PAMS 601 was synthesized by redox initiation. The structure and thermal stability of the copolymer were identified by IRS and DTA-TG. The mud properties of the PA
