The pipeline network of offshore gas fields consists of gas wells,offshore platforms,on-shore terminals,and other units.Each unit is connected by subsea pipelines,which are both indepen-dent and mutually influential.Using LedaFlow and K-Spice to optimize and simulate the operation pa-rameters of the gathering and transportation pipeline network of gas fields can improve the operation ef-ficiency of the gathering and transportation pipeline network,reduce the system energy consumption,and achieve multiple purposes of increasing storage and production,improving quality and efficiency,and saving energy and reducing consumption.Simulation and field-testing results show that reducing the operating pressure of the subsea pipeline can reduce the compressor's energy consumption.It also can reduce the operating pressure of the upstream platform of the subsea pipeline,thereby reducing the back pressure of the producing well and increasing the technically recoverable reserves.Therefore,a set of replicable and easy to promote optimization schemes for the operation parameters of offshore gas field cluster gathering pipeline network is summarized and formed,which has strong practical guiding signifi-cance.
