Question

英语翻译（结果）：结合实际,以外径50.8mm连续管为例,计算分析了二氧化碳在连续管和井筒内温度、压力、密度和相态随井深

Answer 1

Combined with the actual,continuous tube outer diameter 50.8 mm,for example,calculation and analysis for carbon dioxide in continuous tube and wellbore temperature,pressure,density and phase behavior with the change of depth.It is found that continuous tube temperature increases with well depth and rapidly rising carbon dioxide,well depth increased to 300 m,the tube temperature of carbon dioxide and formation temperature is close to,then increases with well depth synchronization with formation temperature,in open hole section and formation temperature difference between the minimum; Ring carbon dioxide in the air temperature distribution in the changing law is similar to the continuous tube,temperature slightly higher than the same depth of continuous tube temperature.Continuous tube is greatest carbon dioxide density in the well's mouth,then with the increase of well depth,co2 density decreases sharply first,after reaching a certain depth,reduce the amplitude is stable,to enter.
