随着国家对天然气的开采以及利用越来越重视,钻井采气工业在现代社会上占有重要地位。在钻井采气工业中,采气井管柱是一项必备设备,保障采气井管柱的正常使用也就有着十分重要的作用。在其使用过程中,不可避免的会受到CO2的腐蚀,掌握CO2腐蚀的速度分布规律以及影响因素对保证采气井管柱正常使用有重要作用。 As the state pays more and more attention to the exploitation and utilization of natural gas, the drilling gas production industry occupies an important position in modern society. In drilling gas production industry, gas well string is an essential equipment to ensure the normal use of gas well string also has a very important role. In the course of its use, it is inevitable that it will be corroded by CO2. It is important to know the regularity of CO2 corrosion rate distribution and its influencing factors to ensure the normal use of the well string.
