采用宏观观察、扫描电镜分析、差热分析（DSC）、红外光谱分析及挂片试验方法对某油田玻璃钢管失效进行分析研究认为主要原因是玻璃钢材料的化学老化。输送介质中原油、CO2和伴生水等成分对玻璃钢中高分子树脂材料的化学交互作用、温度作用以及管道受到的应力作用最终导致有机高分子复合材料的破坏。文章还讨论了玻璃钢管道在腐蚀性环境下使用应注意的问题，评述了在特定工作条件下不同品种玻璃钢管道的性能差异，提出含CO2酸性油气田选择玻璃钢管道产品的一般指导原则。
The failure of FRP pipes in an oilfield was analyzed by macro observation, scanning electron microscopy, differential scanning calorimetry (DSC), infrared spectroscopy and coupon test. The main reason is the chemical aging of FRP materials. The chemical interaction of crude oil, CO2 and associated water in the transmission medium on the polymer resin material in the FRP, the temperature and the stress on the pipe eventually lead to the destruction of the organic polymer composite material. The article also discussed the problems that should be paid attention to when using FRP pipes in corrosive environment. The differences of performance of FRP pipes under different working conditions were reviewed. The general guidelines for choosing FRP pipe products with CO2 acidity were put forward.
