| Abstract (English): |
A transient temperature distribution calculation model of wellbore based on steadystate pressure distribution model and physical parameters of natural gas was established for gas lift operation by injecting natural gas into the annulus of oil casing of offshore oil wells. Combined with the field data, the influence of gas injection temperature, flow rate, components and pressure on the temperature distribution of the wellbore during gas lift was studied and analyzed. The results showed that the injection temperature had a large effect on the temperature distribution in the front part of the wellbore, but the depth of its effect was greatly limited by the interference of seawater. Increasing the injection flow rate led to a significant reduction in fluid temperature in the wellbore. The temperature of the natural gas fluid in the wellbore increased significantly as the CO2 content of the gas components increased with the decrease in CH4 content. Increasing the injection pressure could have an effect on the fluid temperature in the seawater section and had no significant effect on the wellbore temperature in the formation section.

:针对海上油井的油套环空注天然气进行气举作业,建立了基于稳态压力分布模型与天然气物性参数的 井筒瞬态温度分布计算模型。结合现场数据研究和分析了气举注入气温度、流量、组分及压力对气举过程中井筒 温度分布的影响规律。结果表明:注入温度对井筒前段温度分布影响较大,但由于海水的干扰其作用的深度被极 大限制;提高注入流量可以使井筒内流体温度明显降低;随着气体组分中CO2 含量的增加与CH4 含量的减少,井 筒内天然气流体的温度明显增大;提高注入压力仅对海水段井筒温度能够产生影响,对地层段井筒温度无明显 影响. [ABSTRACT FROM AUTHOR] |
