Abstract井筒附近温度的变化对高温高压气井的正常生产存在着明显的影响,塔里木油田高温高压气井的温度变化规律是一个较难解决的问题。为了保证西气东输气源井的正常生产,本文对该问题进行深入研究,建立了一种计算高压气井井筒附近温度的模型,通过有限元计算获得了井筒附近温度的理论曲线;给出了开关井时温度变化的过程,分析了热流密度对高压气井井筒附近温度分布的影响规律。根据气井实际数据计算了产层和非产层外井筒附近温度分布状况并进行了相应的分析,认为产层外井筒附近温度变化比非产层段外井筒附近温度变化幅度小。
Other AbstractThe temperature changes near the wellbore of the high temperature and high pressure well have clear influences on the gas production.In the Tarim Oilfield,the regularity of temperature variation near high temperature and high pressure gas well is a quite difficult problem.In order to ensure the normal gas production for the source wells of west to east gas pipeline,this regularity must be in -depth studied.A mathematical model for calculating the temperature near wellbore of high pressure gas well is established.The theoretical temperature curve near the wellbore is obtained by using the finite element method.The temperature changing rule is given during the open and shut down process of gas well.The temperature distribution near the wellbore is investigated by analyzing the heat flux through the wellbore.Calculation is based on actual data of the producing gas layer and non-producing layer,the wellbore temperature distributions around wellbore are analyzed,respectively.The results show that the changing magnitude of formation temperature in the segment of producing layer is smaller than that in the segment of non-producing formation.
