Synthesis And Structure Research Of Acdification Fracturing Thickener

This paper is to research acrylamide and 2-acrylamide base-2-methyl propane sulf onic acid as raw material synthesis binary polymer (CW-Ⅱ), on the basis of introduci ng acrylic, cyclodextrins etc monomer on modification of polymer synthesis three yuan polymer (CW-Ⅲ) and four yuan polymer (CW-Ⅳ) as a thickener. The experimental results show that to acrylamide,2-acrylamide base-2-methyl propane sulfonic acid, acry lic and beta cyclodextrins according to 10:1:1:1 (quality than) synthetic CW-Ⅳ-2 as a thickener in adding 20% hydrochloric acid content is 2%,30℃in thick acid viscosity when up to 62mPa·s;60℃and 90℃heat stability were 96.8% and 87.1%; In 120℃sh ear force for 170 s-1 conditions shear 60 min viscosity remain after 30 mPa-s, explain CW-IV-2 has good heat shear stability. At the same time it has good salt resistance of different sex and the adaptability of the acid, the experimental results show that th e performance is better than two yuan, three yuan polymer review thickener. The IR and 1HNMR,UV, Raman, TEM and thermogravimetric analysis, elemental analysis, mo lecular weight measurement methods, such as thickeners CW-Ⅳ-2 molecular structures were characterized, discusses the thickener molecular structure on the properties of the influence.
