| 摘 要： | 注二氧化碳提高采收率是一种很具潜力的增油措施,在注入二氧化碳的过程中由于地层和井筒内存在温差,热量会由地层向井筒内传递。主要以注二氧化碳井筒温度场计算模型-注二氧化碳井井筒瞬态温度-压力耦合模型的演变方式为研究目标。

| Abstract: | Carbon dioxide injection enhanced oil recovery is a very potential increase oil measures. In the process of injecting carbon dioxide due to formation and well bore temperature difference,heat will transfer from the formation into a borehole is. Therefore,this paper mainly to CO_2 injection well bore temperature field calculation model evolution as the research target. |
