美国南阿拉巴马州大Escambia河湾（BEC）气田含硫气井的生产环境，由280F、21％的H2S、40％的CO2和在采出水中浓度高达190000ppm的氯化物构成。严重腐蚀的状况迫切要求实现一项缓蚀计划，使这些井安全经济地进行生产。本文描述了井下和集气系统腐蚀防止与监测计划的基本情况、技术研究发展及其成果。该计划内容包括：在腐蚀最严重的井中自环形空间注入水溶性缓蚀剂，以此实现井下的持续性防腐；对其余的井以油溶性缓蚀剂分批处理置换硝化油管；在集气管线中为扩大分批处理，以及在选出的严重腐蚀的井中连续注入一种水溶性缓蚀剂；监测缓蚀剂残余产物并绘制趋势曲线图，以保证井下处理的有效性和优化注入率；以及出口管线内径规和水压试验以监测集气管线的防腐计划。本文还介绍了用于设计、计算和更新连续井下注入系统和硝化分批处理的计算机处理方法。由达到的油管寿命、缓蚀剂残余物的现场数据以及出口管线和井下的内径规，验证了该腐蚀防止与监测计划是成功的。文中提供的数据资料，有助于对严重腐蚀的生产环境的防腐蚀计划进行成功的设计与实施。
The production environment for sulfur-containing gas wells in the large Escambia Bay (BEC) gas field in South Alabama, USA consists of 280F, 21% H2S, 40% CO2 and chlorides up to 190,000ppm in the produced water. Seriously corrosive conditions urgently require a corrosion mitigation plan that will allow these wells to be produced safely and economically. This paper describes the basic situation of the corrosion prevention and monitoring program of underground and gas gathering systems, the development of technological research and its achievements. The plan includes: injection of a water-soluble corrosion inhibitor from a toroidal space in the most corroded well to achieve continuous downhole corrosion protection; batch replacement of nitrified oil pipes with oil-soluble corrosion inhibitors in the remaining wells; In the pipeline, a batch process was extended and a water-soluble corrosion inhibitor was continuously injected into the severely eroded wells. The corrosion inhibitor residual product was monitored and a trend graph was drawn to ensure the effectiveness of the downhole treatment and optimize the injection rate ; And export pipeline internal diameter gauge and hydrostatic test to monitor the anticorrosion plan of the gas gathering pipeline. This article also describes computerized methods for designing, calculating, and updating continuous downhole injection systems and nitrification batches. The corrosion prevention and monitoring program was verified to be successful from the achieved tubing life, on-site data on corrosion inhibitor residues, and outlet gauge and bore gauge. The data provided in this article help to design and implement a successful anti-corrosion program for a highly corrosive production environment.
