Abstract Filter loss reducers presently in use had poor stability and filtration control ability in drilling deep and ultra-deep wells. To overcome these problems, a terpolymer filter loss reducer has been synthesized in laboratory with 2-acrylamido-2-methylpropane sulfonic acid (AMPS), acrylamide (AM), and N-vinyl pyrrolidone (NVP). The optimum synthesis conditions were as follows: molar ratio ofAM : AMPS : NVP = 6 : 3 : 1, concentration ofinitiator = 0.2%, concentrations of the monomers used was 1.5%, respectively, reaction temperature = 50 °C, and the reaction time = 4 h. Structure analysis of the synthesized product with IR spectroscopy showed that it was a terpolymer, and TEM analysis showed that the synthesized product formed an ordered space network structure in water solution. In a 4% fresh water base drilling fluid, the high temperature stability of the synthesized filter loss reducer was remarkably better than that of PAC-LV; the synthesized filter loss reducer functioned effectively at 180 °C
