Abstract：Insomeoilfields，asociatedgasisusuallydirectlyventedduetodispersed gassources，smallgasvolume，andremote distancefromthegastransmisionnetwork，resulting inresourcewasteandenvironmentalpolution.Torealizetherecoveryand comprehensiveutilizationofasociatedgas，theprocessesofcondensaterecoveryandliquefactionwerecombinedandsharedaseof refrigerationcclestoformacoproductionproessofthegassubcooledprocess（GSP）andsteammethanereforming （SMR）andthe redundantequipmentintheproceeswassimplified.Theinfluenceofchangesintheco-productionprocessparametersonthpecific power consumption， liquefaction rate， and C2+ recovery rate was analyzed.Finally，the differences between the single production process andco-productionprocesswerecompared.Theresultsshowthatthelowertmperatureofthelow-temperatureseparatorindicatesthe the higher tower pressure of the demethanizer，smaller gas-phase split ratio，lower specific power consumption and C2+ recovery of the co-productionprocs，andigerliquefactionrate.Teinfueneoftheixingrefrigerantatioonspecificpowerconsumptiondepnds onthechangeofomponentswithalowerboilingpoint.Byotiizingtemiingrefrigerantatioflowrateandrefrigerantpreuete specific power consumption can be greatly reduced. The specific power consumption， liquefaction rate and C2+ recovery of this process are 0.501 4 kW·h/kg， 91.21% and 85.55% ，respectively. Compared with those of the contrast process，the number of equipment is smaller，and the heat transfer of the cold boxis less required.
