为了明确大牛地气田输气管线内是否存在积液，从管道高程、末端分离器排液和管线压降变化三方面进行论证分析。分析表明：液体易于在西1线和中1线内积存，不易在东1线内积存，但末端分离器在清管后没有排过液，且TGNET模拟的理论压降和实际压降差别不大，即西1线、中1线和东1线目前不存在积液；塔榆管线高程整体呈下坡走势，塔榆末站分离器2014年1月—8月没有排过液，且TGNET模拟的理论压降和实际压降差别不大，即塔榆管线存在积液的可能性很小；大杭管线高程平缓，且末端分离器2014年1月—8月没有排过液，不同输气量下TGNET模拟的理论压降与实际压降差别不大，即大杭管线存在积液的可能性很小。

Daniudi gas field pipelines were analyzed in terms of piping elevation,fluid discharge of separators and pressure change to figure out whether effusion existed. The results showed that fluid was more likely to exist in west line 1 and midline 1 than east line 1,but separators didn’t discharge after pigging and TGNET simulations showed tiny difference between theoretical pressure drop and actual pressure drop,which means no fluid exists in these pipelines. Tayu pipeline overall showed a downhill trend,and separators didn’t discharge from January to August in 2014 and TGNET simulations showed tiny difference between the-oretical pressure drop and actual pressure drop,which means the possibility that fluid exists in Tayu pipeline is very small.Dahang pipeline showed a flat trend,and separators didn’t discharge from January to August in 2014 and TGNET simulations showed tiny difference between theoretical pressure drop and actual pressure drop under different throughput,which means the possibility that fluid exists in Dahang pipeline is very small.
