| 摘 要： | 超临界CO2流体的密度较大,与液体接近;其黏度较低,接近干气体.为了研究水平段钻井过程中超临界CO2的携岩能力;建立了描述超临界CO2流体在水平偏心环空中携带岩屑过程的数学模型,同时根据水平偏心环空的特点建立了物理模型.利用CFD数值模拟软件,对不同黏度、不同密度超临界CO2流体在水平井段的携岩规律进行了模拟.计算结果...

| Abstract: | The density of supercritical carbon dioxide is relatively heavy,close to liquid density;its viscosity is small and close to gas viscosity.In order to research the cutting-carrying ability of supercritical carbon dioxide drilling in horizontal section,a mathematical model was built describing cutting-carrying process in the horizontal eccentric annulus with supercritical carbon dioxide;at the same time,the physical model was built according to the characteristics of horizontal eccentric annulus.The cutting-c... |
