摘　　要：对超稠油蒸汽吞吐井注入液态CO2过程中,CO2在井内相态变化以及对油层的热能消耗开展研究,得出CO2主要以液态形式注入油层,在注入过程结束后的4￣6h井底油层温度恢复到接近注入前水平;注入油层的液态CO2在汽化过程中所要吸收的热量为2914.341kJ/kg。根据上述研究结果,对现场实施工艺参数提出指导性建议。This paper studies the phase state alternation and heat energy consumption of oil layer in the process of injecting CO2 in super-heavy oil and cyclic steam stimulated well.h is shown that CO2 is injected in oil layer chiefly in the liquid state.In 4-6 hours after the process of injection,the bottom oil layer tem- perature resumes to the level before injection.The heat of liquid state CO2 injected in oil layer is about 2914.34kJ/kg in the evaporation process.Based on the resuh,it can propose the directory proposal for implementing in field and using the technology parameter.
