| Abstract | 西气东输的气源井以高温高压气井为主，气井生产依赖于井底温度和压力，生产过程中温度起着重要的作用。为了确保高温高压气井的正常生产，必须对井筒温度压力进行深入研究。井筒压力的研究已有较为成熟的结果，但对井底温度的研究还很不成熟，尤其是井身结构对井筒温度的影响国内外尚未见报道。本文基于Ramey经典井筒温度计算模型建立了两种考虑复杂井身结构井的井筒温度分布计算模型，即在复杂井筒条件下从井底到井口的温度计算模型和从井口到井底的温度计算模型。通过与实测资料对比，给出了计算模型的误差对比，分析了井身结构对井筒温度分布计算的影响。研究结果表明，从井底到井口的温度分布模型计算结果优于从井口到井底的温度分布模型。 |
| Other Abstract | The source gas wells for the west to east gas pipeline are mainly high temperature and high pressure gas wells.The production capacity of these gas wells highly depends on the pressure and temperature of well bottom.Temperature in the production process plays an important role.In order to ensure normal production of high-temperature and high-pressure gas wells,in depth study of wellbore temperature and pressure must be carried out.There are many mature research results involving wellbore pressure,however,the study on well bottom temperature is still immature,and especially the impact of complex wellbore on the wellbore temperature has not been reported at home and abroad.Based on the classic Ramey wellbore temperature model,two kinds of mathematical models for calculating the well wellbore temperature distribution in the well with complex structure wellbore are built.The models include the one calculating temperature from well bottom to wellhead and the other calculating temperature from wellhead to well bottom.By comprising with the data of field test,the calculation errors are given,and the impact of the wellbore structure on wellbore temperature distribution is analyzed.The results indicate that the calculating result by using the model from the well bottom to the wellhead is better than that by using the model from the wellhead to the well bottom in the temperature distribution calculation. |
