Scale inhibitors and corrosion inhibitors are therefore frequently applied together to control both risks. However, interactions between different chemicals may produce synergistic or antagonistic effects, thereby altering their performance under combined application. In this study, scale inhibitors and corrosion inhibitors commonly used in the Changqing Oilfield were selected, and experimental platforms were established to evaluate their scale- and corrosion-control performance. Dynamic laser turbidimetry, electrochemical polarization measurements, and the rotating-coupon weight-loss method were employed to systematically investigate the performance of individual chemicals and the interactions within their combined systems. Crystallization induction time, corrosion rate, and protection efficiency were used as the principal evaluation parameters. The results showed that the selected scale inhibitors ZG-1, ZG-4, ZG-5, and ZG-8 exhibited satisfactory scale-inhibition performance, whereas the effects of the corrosion inhibitors varied markedly among the different scale-inhibitor systems. HS-1 exhibited a synergistic effect with ZG-8 but slight antagonistic effects with ZG-1 and ZG-5. HS-2 exhibited antagonistic effects with ZG-1, ZG-5, and ZG-8. Neither HS-1 nor HS-2 had an appreciable effect on the scale-inhibition performance of ZG-4, indicating relatively good compatibility with this inhibitor. Conversely, most of the tested scale inhibitors had little influence on the corrosion-inhibition performance of HS-1 and HS-2 and did not cause an evident increase in corrosion rate. Among them, ZG-5 slightly decreased the corrosion rates of both corrosion-inhibitor systems and increased their protection efficiencies, demonstrating relatively favorable compatibility. Based on these experimental results, scale inhibitor–corrosion inhibitor interaction matrices were constructed to provide a direct representation of the synergistic, antagonistic, or negligible effects of different chemical combinations. The resulting matrices can provide a practical basis for compatibility screening, formulation design, and optimization of chemical-dosing strategies in oilfield operations.
