摘　　要：湿天然气长距离混输技术在实际生产中已经得到越来越广泛的应用。为了研究湿天然气管道输送的流动情况,采用OLGA软件模拟了海上某区块气田的湿天然气长距离混输管线生产工况,并进行了管线流动分析。研究结果表明:入口气体流量的变化与管内积液量变化成反比;在入口流量增加的过程中,密度波的传播速度小于压力波的传播速度,反之,密度波的传播速度大于压力波的传播速度。Wet natural gas long-distance mixed transmission technology has been more and more widely used in actual production.In order to study the flow of wet natural gas pipeline transportation,OLGA software is used to simulate the production conditions of wet natural gas long-distance mixed pipelines in a certain offshore gas field,and pipeline flow analysis is conducted.The results show that the change of inlet gas flow is inversely proportional to the change of liquid volume in the pipeline.And in the process of inlet flow increase,the propagation speed of density wave is smaller than that of pressure wave.On the contrary,the propagation speed of density wave is greater than that of pressure wave.
