The effect of multi-component Inhibitor systems on hydrate formation

Based on the existing components of drilling fluids, the construction of a multi-component hydrate inhibitor system is essential for building a high-performance hydrate drilling fluid system and reducing production costs. The constant rate cooling method are performed to investigate the effect of different inhibitor systems on hydrate formation. The results indicate that thermodynamic inhibitors exhibit enhanced effectiveness in inhibiting hydrate formation at higher mass concentrations. In contrast, kinetic inhibitors demonstrate superior performance at lower mass concentrations, and their inhibitory efficacy does not scale up with concentration. Kinetic inhibitors can synergize with other components of the drilling fluid that have thermodynamic inhibitor effects. In particular, the ternary composite system has better synergistic effects compared to the binary composite system. It is of great significance for the construction of efficient hydrate drilling fluid systems in the future.
