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 come to the conclusion, in the same well. Slow release agent, relatively high concentration, is good for the inhibition effect, the higher the better.Because 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. Key words：orrosion inhibitor；Liquid production rate；Dynamic conditions of inhibitor action；Effect of Corrosion inhibitor  目 录 第章引言 1 3 2.1 腐蚀的概念与分类 3 2.2 CO2腐蚀概述 3 2.2.1 CO2腐蚀的定义 3 2.2.2 CO2腐蚀的机理 4 2.2.3 CO2腐蚀的影响因素 5 2.3 缓蚀剂概述 6 2.3.1 缓蚀剂的定义 6 2.3.2 缓蚀剂的分类 6 2.3.3 CO2缓蚀剂的作用机理 7 2.3.4 CO2缓蚀剂缓释作用的影响因素 8 2.4 国内外的研究现状 9 2.5 本课题的研究内容以及目的意义 9 第3章 实验装置以及实验步骤 11 3.1 试验主要装置 11 .2 实验主要过程和参数调节 12 .3 试验方案 12 12 3.3.3 油帽子高度对缓蚀剂扩散规律的影响 13 第章 14 4.1 加药浓度对缓蚀剂扩散规律的影响
