• ABSTRACT Based on the requirement of the synthesized polymer resistant to higher temperature and lower cost demand of water‐based drilling fluid system, a novel polymer, which named poly(AMPS/AM/SSS), was synthesized using acrylamide (AM), 2‐acrylamido‐2‐methylpropanesulfonic acid (AMPS), and p‐styrenesulfonate (SSS). At first, the molecular structure was investigated through Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance hydrogen spectroscopy (1H‐NMR) and element analysis. Simultaneously, the molecular weight and distribution was obtained by gel chromatography method. Moreover, the thermal stability was produced by thermal analysis (TG). Secondly, the poly(AMPS/AM/SSS) was introduced into water‐based drilling fluid system. As a result, it was shown that the use of poly(AMPS/AM/SSS) significantly improved the filtration performance of drilling fluid system. When the adding amount is 1.2 wt %, the FLAPI of drilling fluid system is 9.20 mL. Moreover, it was found that the flow curve of water‐based drilling fluid systems are more fitted to the Herschel–Bulkley flow model. Besides, the temperature resistance of water‐based drilling fluid system was obviously improved. Furthermore, it was confirmed that the cost of water‐based drilling fluid system was significantly reduced. During this study, the filtration mechanism of the synthesized poly(AMPS/AM/SSS) was studied by adsorption analysis, Zeta potential method, and morphology analysis. © 2018 Wiley Periodicals, Inc. J.
