耐腐蚀连续油管是一种缠绕在滚筒上,可连续下入或从油井起出的一整根无螺纹连接的长油管,广泛应用于石油天然气勘探开发,修井等作业中.目前我国多数油气田的硫含量较大,称之为高硫油,硫化氢,Cl-等介质容易造成油管的腐蚀,为此探讨和研究连续油管在含硫物质中氢致开裂,硫化物应力腐蚀开裂和沟腐蚀性能对连续油管的选材,加工工艺制造和耐腐蚀连续油管的应用等有较大的现实意义;特别是结合生产实际要求,对同材质的进口和国产两种油管进行腐蚀分析与评价,为国产连续油管的生产和应用提供基础和数据.本文采用美国腐蚀工程师协会NACE标准TM0284-2003《管道,压力容器钢抗氢致开裂性能评价的实验方法》,并参照国标GB/T9711.3-2005《石油天然气工业输送钢管交货技术条件第三部分:C级钢管》进行实验.对进口和国产两种同类材质的连续油管的母材和焊缝分别取样,研究了连续油管在硫化物介质下的氢致开裂,硫化物应力腐蚀开裂和沟腐蚀行为;分别借助金相显微镜,扫描电镜(SEM)和能谱仪(EDS)研究焊接接头的组织,断口形貌,断口元素组成,从环境因素,材料组织,化学成分等方面对连续油管断裂机理进行了分析和探讨.主要研究结论如下:国产GC耐腐蚀连续油管与进口连续油管JK均对氢致开裂不敏感,抗氢致开裂能力均满足标准要求,具有较强的抗氢致开裂性能;进口连续油管的焊缝腐蚀沟较窄。
从耐腐蚀连续油管的材料、制造技术及作业技术等方面概述了连续油管的发展和应用情况,重点分析了TMCP态超高强度连续油管、调质型连续油管、耐腐蚀连续油管的技术发展趋势.分析指出,连续油管的市场前景良好,并且随着油气的深入开采和井况的日益复杂,从而对连续油管的规格及性能提出了更高要求;当前主要形成高强度低合金钢系列的连续油管,并出现了高耐蚀合金、复合材质以及调质型等多个系列的发展方向;未来连续油管的规格将向更大直径和长度的方向发展,性能向更高强度、更长疲劳寿命和更优耐蚀性方向发展,同时将更加关注产品的经济性及可制造性。
