【正文】 diffusion law Abstract In the process of oil production, due to the presence of carbon dioxide, will produce some corrosion on our production equipment, our equipment leads to rapid aging, shortened life expectancy. We use to reduce the corrosion inhibitor, and thus relatively extend the life of equipment. The inhibitor effect, there are many related factors. Such as liquid production rate, slow release agent concentration, oil cap height, oil content and many other factors. Simulation in the underground production process by fluid flow, the main task is to study the corrosion inhibitor concentrations in different situations, different results of corrosion inhibitor and the effect, at the same time we also done on the influence of oil content on its function, and finally we e to the conclusion, in the same well. Slow release agent, relatively high concentration, is good for the inhibition effect, the higher the the production of oil is mainly in the dynamic condition, the success of the will is our production level in the last step, will greatly reduce the damage to the equipment, to provide a reference method, filling and can to a certain extent for oilfield corrosion inhibitor dosing and dosing period.
