摘要
两性离子聚合物 (ampholyticpolyelectrolyte)通常是指大分子链上同时带有阴、阳离子基团的高分子化合物。它作为一类新型油田高分子化学剂 ,其应用广泛 ,发展潜力巨大。本文主要介绍了两性离子聚合物在钻井液处理剂 ,压裂液添加剂、固井水泥外加剂、强化采油化学剂方面的应用、分子类型及发展现状 。
The ampholytic polyelectrolytes are generally polymers with both anionic and cationic groups on their macromolecular chains.As a new type of oil field polymer chemcals,they can be used widely and have great development potentialities.This article mostly introduces ampholytic polyelectrolytes’applications,molecular types and development actuality in drilling treatment agents,fracturing additives,cementing extra-agents and enhanced oil recovery chemicals.In addition,the function mechanism of the new polymers is illuminated.
