This paper introduces that the HTHP CO2/H2S conditions were experimentally simulated,the corrosion behaviors and the produced corrosion films on L80 steel of tubing or casing were investigated by weight loss method,SEM and EDS methods.

• 为此,以实验手段模拟油气开发中高温高压H2S/CO2共存环境,用失重法、SEM和EDS研究了油管、套管L80钢材的腐蚀规律以及腐蚀产物膜。
