Gongye shui chuli, 2009 吉林油田乾安采油厂腐蚀结垢问题是长期困扰该油田稳产高产的主要问题,国家工业水处理工程技术中心通过对现场腐蚀结垢特点及现场采出液水质、油井产出气、垢样及细菌含量进行全面细致的分析后,得出结论:该油田油井系统以腐蚀为主,造成腐蚀的原因主要是硫酸盐还原菌腐蚀并伴有轻微的电化学腐蚀,部分区块存在CO2.腐蚀。在此基础上进行了杀菌剂及缓蚀剂的筛选,筛选结果表明:新型有机硫杀菌剂TS-782A、聚季铵盐类杀菌剂TS-838具有优异的杀菌效果,新型咪唑啉类复合缓蚀剂对CO2.腐蚀具有良好的抑制作用。

Shiyou jixie, 2015 针对三高气田套管腐蚀难题，分析了套管腐蚀失效因素，设计了应力腐蚀试验方法。用TP110TS和TP95S套管试样，模拟现场井下条件进行不同拉应力、无应力和压应力状态下套管腐蚀试验，并根据试验结果对套管应力腐蚀速率的主要影响因素、腐蚀后力学性能、应力腐蚀敏感性和应力腐蚀门槛值及安全性进行研究。研究结果表明，三高气田套管腐蚀不可避免，拉应力对应力腐蚀具有敏感性；随着拉应力、H2S和CO2含量的增大，套管腐蚀速率加快、力学性能退化，导致其服役安全寿命缩短。据此提出了采用组合套管 ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Aqueous zinc‐ion batteries are plagued by anode challenges such as dendrite growth and corrosion, which stem from intrinsic surface heterogeneity. Although constructing a homogeneous interfacial layer is a promising strategy, conventional electrolyte additives often suffer from incomplete or unstable coverage.
