含硫气田油管防腐技术研究 Antisepticize technique research of oil tube in sulfurous gas filed
清洗世界 第25卷第4期 防腐救恭 World 2009年4月 Cleaning 文章编号:1671—8909(2009)04—0031一07 含硫气田油管防腐技术研究 胡新河1 廖如刚2 朱志芳2 (1.中石化江汉油田分公司水电厂,湖北潜江433123; 2.中石化江汉油田分公司采油工艺研究院,湖北潜江433123) 摘要:建南气田以前从未系统地开展过油管选型研究,管柱腐蚀严重,部分气井油管下井不到 一年便腐蚀断脱。通过对当前井下管柱腐蚀原因的分析,结合油管挂片和拉伸试验研究成果, 优选出适合于建南气田自身特点的油管,为气田安全生产起到良好的促进作用。 关键词:天然气井;防腐;油管;硫含量 中图分类号:TE988.2文献标识码:A in researchofoiltubesulfurousfiled Antisepticizetechnique gas HU Xinhel,HAo Rugan营,ZHUZ蜘营 Plantof Oilfield 4331 (1.HydropowerJianghan Company,SINOPEC,Qianjiang,Hubei23,China; 2.Production ResearchInstituteof Oilfield Technology Jianghan Company,SINOPEC, 433 Qianjiang,Hubei123,China) in fieldneverhad researchabouttube selectionthebefore.
