牙哈301井油管腐蚀原因分析
Cause Analyses of Tubing Corrosion in Yaha 301 Well
摘 要
对牙哈301井油管腐蚀原因进行了调查研究,对油管腐蚀形貌和分布规律进行了分析,对油管材质进行了试验.通过调查研究和试验分析,认为油管为二氧化碳腐蚀,腐蚀介质来源于天然气中的二氧化碳和凝析水,腐蚀严重程度和分布规律与油管结构和井深位置有关.

Abstract
The tubing corrosion reason was analyzed based on the examination of tubing corrosion morphology and distribution,as well as the material composition.The tubing corrosion was caused by CO2.The corrosion mediaum of CO2 and condensate water came from air.The corrosion degree and distribution feature were related to the tubing configuration and the depth of the well.
