Preparation of a Cationic Hyperbranched Polymer for Inhibiting Clay Hydration Swelling in the Process of Oilfield Waterflooding

Abstract: In this paper, preparation and the inhibition properties of a cationic hyperbranched polymer (HBP-HTC) on clay hydration and swelling were researched. The properties of HBP-HTC, including chemical structure, cationic degree, and molecular weight, were investigated by using Fourier transform infrared (FTIR) spectroscopy, nuclear magnetic hydrogen spectroscopy , sodium tetraphenylborate back titration, and gel permeation chromatography. The obtained results indicated that HBP-HTC was a hyperbranched unsaturated … Show more
