摘要:
利用弃井开采地热能,可以充分发挥我国现有大量被弃油井的价值,有助于解决能源短缺问题,为我国绿色能源的发展提供参考依据。文章建立了弃井内换热的物理模型,将其应用于利用弃井开采中深层地热能名义取热量的模拟,研究了循环水流量、弃井深度、外管管径、外管导热系数、中心管管径及中心管导热系数对换热器名义取热量的影响。结果表明:改造后的弃井换热器对中深层地热能的名义取热量会随着循环水流量和钻孔深度的增大而增加;名义取热量随着外管管径以及外管导热系数的增大而增加,最后趋于定值;并随着中心管管径和导热系数的增加而减小。
Abstract:
With the global energy shortage, more and more attention was paid to the development of geothermal energy. In view of the current situation of a large number of abandoned oil wells in our country, this paper presents a simulation study on the utilization of the deep geothermal energy in the injection and production of abandoned oil wells. The mathematical and physical models of heat transfer in abandoned oil wells are established on the bases of analysis and simplify of the retrofitting abandoned oil wells. The effects of circulating water flow, abandoned well depth, outer pipe diameter and thermal conductivity, central pipe diameter and thermal conductivity on nominal heat transfer of heat exchangers were studied by numerical simulation. The results show that the nominal heat of abandoned well heat exchanger increases with the increase of circulating water flow, drilling depth, outer pipe diameter and thermal conductivity of outer pipe, and decreases with the increase of central pipe diameter and thermal conductivity.
