耐温抗盐耐剪切型滑溜水降阻剂的制备探讨

摘要

针对耐温、抗盐、耐剪切型降阻剂的制备提出一些具体的思路.列举了一些可以提高耐温抗盐性的单体,例如含有强电解质基团的单体,包括乙烯基磺酸、丙烯基磺酸、乙烯基苯磺酸、2-丙烯酰胺基-2-甲基丙磺酸;还有含有环状结构的单体,包括N-乙烯基吡咯烷酮、壳聚糖、乙烯基糖苷、乙烯基β-环糊精、N-烯丙基咪唑、丙烯酰吗啉等.另外,乳液型疏水缔合丙烯酰胺共聚物既具有良好的溶解性也具有较好的抗剪切性.%The paper proposes some practical ideas to prepare friction reducer with temperature,saliniy and shear resistant.We list some monomers which can improve temperature and saliniy resistance.Some monomers include strong electrolyte group,for example,sodium vinylsulfonate,sodium allylsulfonate,sty-rene sulfonate and 2-acrylamido-2-methylpropane sulphonate.Some monomers include loop structure,for example,N-vinyl pyrrolidone,chitosan,vinyl glycoside,allyl-β-cyclodextrin,1-allylimidazole and 4-acrylo-ylmorpholine.In addition,emulsified hydrophobic associating polyacrylamide exhibit good solubility and shear resistance.
