Research on Influencing Factors of Liquid Accumulation in a Low-Pressure Gas Field Gathering Pipeline
摘要
Abstract
A low-pressure gas field employs a low-pressure wet gas gathering and transportation process.The gas at the wellhead is typically water-saturated,and the pipeline route traverses areas with undulating ter-rain and significant seasonal temperature variations.These conditions make the pipeline prone to liquid accumu-lation,leading to reduced transportation efficiency and potential safety hazards,such as hydrate freezing and corrosion,which ultimately impair the efficient development and safe operation of the gas field.Currently,the research on liquid accumulation patterns in low-pressure gas field gathering pipelines remains insufficient,and factor analyses are often confined to single parameters.Therefore,a simulation analysis was conducted on se-verely affected pipelines within this gas field to investigate the influence of inlet gas flow rate,mass liquid hold-up,inlet temperature,outlet pressure,and ambient temperature on liquid accumulation.Orthogonal experi-ments were then employed to examine the degree of influence of each factor and their interactions.The results indicated that the liquid accumulation volume was positively correlated with mass liquid holdup and outlet pres-sure,and negatively correlated with inlet gas flow rate,ambient temperature,and inlet temperature.Mass liq-uid holdup had the most significant impact on liquid accumulation,while inlet temperature had the least.The interaction between the inlet gas flow rate and the mass liquid holdup also significantly influenced liquid accu-mulation.The findings provide a scientific basis for preventing and controlling liquid accumulation in low-pres-sure gas field gathering pipelines and offer guidance for the design and long-term safe and stable operation of such pipelines in complex terrain.关键词
