摘　　要：输送介质为天然气和凝析油的多相流混输海底管道,在正常运行时,由于管内气液分层流动,管道沿程的压降较小。在清管操作时,受立管处累积的液量和段塞流的影响,管道入口压力上升,可能超过正常运行时的压力。本文利用国际先进的OLGA软件,对清管过程中的压力、流量变化进行数值模拟,为混输海管的设计提供了理论依据。For the gas and condensate multiphase subsea pipeline,the pressure drop along the pipeline is small because of gas-liquid stratified flow during normal operation.In the pigging operations,pipe inlet pressure may exceed the normal operation pressure for the cumulative fluid in riser and slug flow.In this paper,the OLGA software is used to simulate the pressure and flowrate variation in pigging operation,the results will provide a theoretical basis for the design of multiphase subsea pipeline.
