摘要
将井筒热对流与地层热传导相结合,给出了井筒温度分布,推导出考虑变温影响的试井解释新方法,剖析焖井过程中油层和蒸汽的能量变化,并使用热流耦合典型曲线,对焖井试井压力资料进行试井分析,解释的参数能够较好的指导蒸汽吞吐井吞吐参数调整,有利于提高吞吐效果。
In this paper, wellbore temperature distribution is calculated by combining the thermal convection of wellbore and thermal conduction of formation. On that basis, a new method is derived for well test interpretation that takes into account the influence of transient temperature. Moreover, energy transfer of formation and steam is analyzed during the stage of stewing. By the aid of the typical curve of thermal-flow coupling, stewing pressure data are used to carry out interpretation. The interpretive results can be used to guide the adjustment of parameters of huff and puff to increase the effect.
