Simulation Experiment of Different Injection Modes of High Sour Gas Well Corrosion Inhibitor

The effect of injection modes on corrosion inhinition efficiency of the imidazoline and organic amine comlpex inhibitor under the condition of simulating gas-gathering line system of high sour gas well was evaluated by using SEM and XRD.The results indicated that the corrosion inhibition efficiency for three different injection modes was all above 75% and the mode of coating + one-off injection was the best.
