In the process of natural gas transportation, the existence of free water is a disturbing problem. This paper studies the calculation model of the natural gas water content of the China-Russia eastern gas pipeline and the amount and distribution of fluid accumulation in the China-Russia eastern gas pipeline commissioning stage. By comparing the calculation, Li correlation with the Keenan-Keyes model is a suitable model for calculating the natural gas water content of the China-Russia eastern gas pipeline. According to the model and software calculation, under the winter conditions in the first year of production of the China-Russia eastern gas pipeline, the total water accumulation in the pipeline increases with the increase of water content. The water produced in the pipeline can reach 255 × 10 3 m 3 in the case of saturated water content in the first year of production. The water accumulation in the pipeline is mainly distributed in the ascending part of the low-lying pipe section. Where the height difference of the pipeline is greater, the water accumulation is more serious. In the pipeline section with a mileage of 53km - 134km, the water accumulation was the most serious, and the liquid holdup was as high as 0.66.
