应用油藏工程、热传递基本理论剖析了焖井过程中油层和蒸汽的能量变化,详细描述了稠油蒸汽吞吐开采过程中焖井阶段的特点,推导出考虑温度效应影响的三区复合油藏的试井模型,并对现场测试中焖井资料进行了分析,解释的参数能够较好地指导蒸汽吞吐井吞吐参数调整,提高吞吐效果。%In this paper, we dissect energy alternation of the layer and steam with reservoir engineering and heat conduction theory, describe the features of the soaking stage during the exploration of steam stimulation for heavy oil in detail. Finally, we can deduce well test models for three districts composite reservoir considering the influence of variable temperature, and analyze test data of soaking wells, the results of which can be guidance for the parameter adjustment of cyclic steam stimulation wells, so as to improve the huff and puff efficiency.
