Under the background of"dual carbon",higher requirements are put forward for oil and gas development and production of offshore platforms.Due to the slug flow(slug gas/slug liquid)easily formed in the multi-phase mixed sea transport pipe of wellhead and central treatment platform,and limited by the capacity of the compressor unit's return regulating valve,the accidental blowout of the slug gas is regulated by automatic loading/unloading of the compressor unit,resulting in resource waste and increased carbon emissions.Based on the advantages of the connected platform,the paper reformed the new natural gas system to form a"triple regulation mechanism"for the recovery of sea pipeline slug gas.The results show that:Based on the"triple regulation mechanism",the maximum instantaneous discharge of slug gas is reduced by 93%to 100%,basically realizing zero discharge recovery,effectively improving the stability of the process,ensuring the smooth operation of large equipment of the compressor unit,and having certain reference significance for the optimization design of the offshore connected platform.
