| 摘 要： | 采用超临界CO_2压裂技术能较好地改造塔河油田水敏、低渗储层,而压裂过程中井筒和裂缝温度场对CO_2物性参数影响较大,需要对CO_2压裂温度场进行研究。考虑径向非稳态传热、轴向非稳态对流以及摩擦力、黏滞力的影响,推导了井筒温度、压力方程,结合K-D-R方法和CO_2物性模型,建立了CO_2压裂过程中井筒和裂缝温度场计算模型,并通过实测温度、压力数据拟合,验证了模型的准确性。应用所建模型分析了塔河油田胡杨2井CO_2压裂施工排量对温度场的影响,结果表明:CO_2注入排量对井筒温度、压力以及裂缝温度影响明显,而对裂缝内压力影响较弱;井筒压力梯度随着排量增大而变小;井筒和裂缝中CO_2均可存在液态和超临界态2种相态。研究成果能为塔河油田CO_2压裂施工设计优化提供一定指导。
