| 摘 要： | 基于注水过程中的腐蚀理论,综合考虑影响注水过程中腐蚀的几个重要因素,如含盐量、溶解氧含量、硫化氢含量及细菌作用,采用室内腐蚀实验综合评价及软件模拟预测方法,对QHD32-6油田注入水的腐蚀作用进行评价.室内实验研究表明,注入水综合腐蚀速率平均为0.037 7 mm/a,因此注水系统的腐蚀指标是达到标准的中偏低水平.利用预测软件,根据产出污水的实际运行数据给出FPSO平台管线、海管输送和注水井3种情况的腐蚀预测结果,基本与室内实验情况相符. |

| Abstract: | Based on the corrosion theory of the process of injection,The injected water corrosion of Qin Huangdao 32-6 oil field was evaluated.It considered several important factors affecting the corrosion of the injection process,such as salinity,dissolved oxygen content,hydrogen sulfide content and bacterial action,and adopted the methods of the indoor corrosion experiments evaluation and using simulation software to predict.Experimental research show that the average corrosion rate of the injected water is 0.037 7 mm/a,so the corrosion index of the injection system is up to standard in low level.According to the actual running data of the produced water,using software to predict the corrosion of three cases,such as FPSO platform pipeline,sea tube transport and injection wells,whose results were consistent with that under the indoor experimental condition. |
