Abstract: Frequent leakages are found with the anti-corrosion alloy premium connection for the oil tubing and casing due to abnormal make-up,which is regarded as a potential safety hazard. Based on the sealing principle of the premium connection tubing and casing,and the properties of the anti-corrosion metal material,the common causes for the leakage as above mentioned are analyzed. And improvement measures are proposed to reduce even eliminate the make-up abnormality,involving such aspects as control and inspection of the thread shape,sufaced copper-plating treatment and site application etc,which brings about a reference significance for the design,site application and abnormality analysis of the anti-corrosion alloy premium connection.
