摘要
气田之产物除了天然气,凝析油外,常伴随有水、H_2S、CO_2、盐分、酸、沉积物等腐蚀性物质,这些腐蚀性物质对气田开采大量采用的钢制设备具有很强的腐蚀性。一旦发生腐蚀破损,不仅造成经济损失,而且危及人身安全。因此正确实措防腐蚀技术是保证气田安全生产的重要举措。本文着重探讨酸性天然气—气田水腐蚀的现象和类型;气田钢制设备腐蚀破坏的特点及典型破坏事例,影响腐蚀的因素及其防腐蚀措施。
As products of gas field, natural gas and gas condensate contain some corrosive contaminants,as H2O,H2S,CO2,salt,acid,deposits,etc. Such contaminants have serious corrosivity for a large number of steel equipment used in gas field. Corrosvie breakdown can cause economical losses and endanger personal safety. Therefore,it is necesary to take correct corrosion prevention measures to ensure safe production in gas field. This paper discusses corrosion appearances and categories from acid gas field water,corrosion breakdown charactenistics of steel equipment in gas field,factors having an effect on corrosion and corrosion prevention measures..
