摘要:
为应对湿天然气管道存在的明显积液，导致管材腐蚀，目前经验性的检测点选择方式导致检测成本和工作量过大问题。基于某单井站场工况条件和现场壁厚检测数据，针对站场主管线，采用Fluent软件建模分析管线内液相分布规律。结果表明：含液率大小随原料气含水量、流量、压力的变化而呈正相关变化，运用Correl函数对现场壁厚检测数据和模拟结果进行对比验证，发现两者的相关度达到0.61以上，这为现场合理选择腐蚀检测点提供依据，降低了现场检测工作量和检测成本。
Abstract:
In order to deal with the problems that the obvious liquid accumulation in the wet natural gas pipelines leads to the pipe corrosion,and the empirical selection method of detection points leads to the excessive detection cost and workload,based on the working conditions and on-site wall thickness test data of a single well station,the modeling and analysis on the liquid phase distribution laws in the main pipeline was conducted by using the Fluent software.The results showed that the liquid holdup was positively correlated with the change of water content,flow rate and pressure of the feed gas,and the Correl function was used to compare and verify the on-site wall thickness test data and simulation results.It was found that the correlation between the two was more than 0.61,which provided a basis for the reasonable selection of on-site corrosion detection points,and greatly reduced the on-site detection workload and cost.
