摘　　要：针对污水回注井套管内壁、油管外壁腐蚀结垢严重的问题。采用腐蚀挂片、多臂井径仪测试腐蚀速率及程度,并研究复配套管复合保护液通过污水回注井油套环形空间添加保护液,在油管外壁、套管内壁表面形成保护膜,减少腐蚀介质与金属接触的机会,达到延缓污水回注井油管和套管腐蚀的目的。In this paper,wastewater re-injection well casing wall,tubing outer wall structure of a serious corrosion problems.Hanging with corrosion films,multi-arm caliper corrosion rate and extent of testing and to study the re-matching tube composite protective solution. Wastewater re-injection wells through the annular space casing to add protection solution,in the outer wall tubing,casing inner wall surface of the protective film to reduce contact with the metal corrosion media the opportunity to delay the water re-injection well tubing and casing corrosion purposes.
