摘要
Abstract
At present,conventional hydraulic tongs was widely used on casing for on/off operation,which increases the work efficiency and reduces the labor intensity of the operating workers,but it also creates a new problem of scratching the outer wall of the casing. Once there is obvious bite on the surface of the casing,the protecting coating on the surface of the casing will be damaged. The corrosive gas such as H2S will speed up the casing corrosion and reduce the service life of the casing. This article mainly studies the type of casing corrosion,hydrogen sulfide corrosion,corrosion-resistant casing materials,etc. to reduce the casing damage and improve the service life of the casing.关键词
