第一章聚丙烯酰胺及其部分水解物聚丙烯酰胺及其部分水解物有很多可贵的性能,如絮凝、增稠、粘附、分散及成膜性等等。所以,在矿业、冶金、化工、污水处理及土壤改良等方面用得十分广泛。在石油开发过程中,用得也很多,如钻井泥浆、油田注水、及破乳等。本文谈它们在钻井泥浆中的应用。第一节化学结构什么是聚丙烯酰胺及其部分水解物? 聚丙烯酰胺是一种高聚物。它是由很多个丙烯酰胺分子通过聚合反应“聚”起来的,
Chapter polyacrylamide and its partial hydrolyzate Polyacrylamide and its partial hydrolyzate have many valuable properties, such as flocculation, thickening, adhesion, dispersion and film-forming and so on. Therefore, it is widely used in mining, metallurgy, chemical industry, sewage treatment and soil improvement. In the process of oil development, there are also many uses, such as drilling mud, oilfield water injection, and demulsification. This article talks about their use in drilling mud. Section chemical structure What is polyacrylamide and its partial hydrolyzate? Polyacrylamide is a polymer. It is a lot of acrylamide molecules through the polymerization reaction “together”
