Abstract A GO/polymer filter loss reducer GOJ was made through copolymerization of graphene oxide (GO), acrylamide (AM), 2-Acrylamido-2-methylpropane sulfonic acid (AMPS), dimethyl diallyl ammonium chloride (DMDAAC) and vinyl acetate (VAC). Characterization of the synthesized product with IR and TEM photography showed that there are pentacyclic structure and amide group, sulfonic group, hydroxyl group in the GOJ molecules. GOJ has relative molecular weight of about 3.63 × 10°. Observed under the microscope, GOJ has dark color and a levelling platy structure. Drilling fluid laboratory experiment showed that GOJ has good filtration control property. A fresh water base drilling fluid treated with 0.2% GOJ has its API filter loss reduced by 70%, indicating
that theperformance of GOJ is better than PAMS601

salt resistant, and can be used in saturated salt drilling
fluid. At the same concentration in drilling fluid, the filtration rates of the drilling fluids treated with GOJ under 180 °C, 200 °C and 22o °C are all lower than that of the drilling fluids treated with Driscal-D under the same temperature, respectively. Graphene oxidc has the ability to enhance the temperature resistance of GOJ; when GOJ contains 0.32% graphene oxide, the temperature resistance of GOJ is increased by about 20 °C, and with the increase of the content of graphene oxide in GOJ, the high temperature filtration control performance of GOJ is also increased.
