| 摘 要： | 川东气田在开发含酸性气体（硫化氢、二氧化碳等）腐蚀介质的油气构造中，油管腐蚀问题十分突出。由于油管在井下所处环境十分复杂，腐蚀影响因素众多，因此产生的腐蚀现象千奇百怪，不胜枚举。怎样从这些花样繁多的腐蚀现象中，总结出油管腐蚀发生与发展的变化规律，是解决油管腐蚀问题的关键环节。本文利用生产现场实际资料的归纳整理，结合机理分析，阐述了川东气田油管腐蚀现象的基本特征，为指导油管防腐工程实践提供了可靠的依据。

| Abstract: | The problem of tubing corrosion is very outstanding in exploiting the oil and gas containing sour gas corrosive medium (H 2S and CO 2,etc.) in Chuandong gas field.Because the surroundings in which the downhole tubing is placed are very complex and there are many corrosive factors,the corrosion phenomena are various and too numerous to enumerate.Summarizing the variation law of tubing corrosion occurrence and development from various corrosion phenomena is a key link for solving the problem of tubing corrosion.In this paper,through summing up and sorting out the practical data from worksite and combining with mechanism analysis,the essential features of the tubing corrosion phenomena in Chuandong gas field are expounded,providing a reliable basis for guiding the anticorrosion engineering for tubing. |
