Abstract
A polymer, a thickening agent, and a preparation method therefor are provided. The polymer contains structural units of formula (1), of formula (2), of formula (3), and of formula (4): The thickening agent contains the polymer and has instant solubility. It can be used for thickening slickwater, a glue solution, a cross-linked fracturing fluid and an acid solution having different viscosities, which improves compatibility between different fracturing fluids. Various fracturing fluid systems prepared by using the thickening agent have good temperature resistance, shearing resistance, sand-carrying performance, and a slow speed.
