酸性天然气集输管道常采用加注缓蚀剂进行防腐，并在缓蚀剂连续加注的同时，还定期进行清管和预膜以保证缓蚀剂防腐工艺效能。本文概述了酸性天然气集输管道预膜技术，包括缓蚀剂的选型、常用预膜工艺和预膜用量计算，分析了湿气管道缓蚀剂预膜技术的特点，并结合工程实践提出了预膜工艺技术要求和效能评估方法。
痠性天然氣集輸管道常採用加註緩蝕劑進行防腐，併在緩蝕劑連續加註的同時，還定期進行清管和預膜以保證緩蝕劑防腐工藝效能。本文概述瞭痠性天然氣集輸管道預膜技術，包括緩蝕劑的選型、常用預膜工藝和預膜用量計算，分析瞭濕氣管道緩蝕劑預膜技術的特點，併結閤工程實踐提齣瞭預膜工藝技術要求和效能評估方法。

Filling corrosion inhibitor is a kind of universal method in anti-corrosion technology of sour gas gathering and transfering pipelines. Pigging termly and batching technology should be conducted in order to ensure the efficiency. The lectotype of inhibitor, frequently-used of batching technology and calculation of batching of corrosion inhibitor were discussed in this paper .The characteristics of batching technology used in wet sour gas environment were analysed. The technical requirements and performance evaluation of batching technology were presented with the combination of engineering practice.
