| 摘 要： | CO2地质封存是减少二氧化碳排放的有效途径之一,井口压力的大小直接关系到封存项目的有效性和安全性。本文总结了井口压力求取的常规方法和漂移流模型解析法,并在实际封存场地进行了比较应用分析,结果发现漂移流模型解析法对井中流体运动刻画的更为准确,所得的结果与实际值更接近,而且井径大小对井口压力有一定程度的影响,其结果可为实际CO2地质封存项目的实施提供技术支持。

| Abstract: | Geological sequestration of CO2 is one of effective approaches to reduce CO2 emission. The Value of the wellhead pressure is directly related to the safety and effectiveness of the whole project. This paper first summarized the conventional method and the drift-flux model, and then applied these methods to a practical CO2 geologic sequestration project. The results demonstrate that the drift-flux model can subtly characterizes the fluid flow in the wellbore and has a better precision, the analytical values using the drift-model are much closer to the actual value, and the wellbore inner diameter has a certain degree of effect on the wellhead pressure. The findings could provide technical support for CO2 geologic sequestration project. |
