| 摘 要： | 基于注二氧化碳混相驱试井分析理论,分析了二氧化碳与原油混相过程中混合物组分的扩散模型和温度、粘度的变化规律,研究了此过程中组分突变与温度突变（粘度突变）对压力的影响,将压力变化分成了求解两区复合试井模型得到的压降和由温度与粘度突变引起的附加压降。通过推导,给出了井底的整体压力响应;利用数值反演方法,计算了考虑组分与粘度...

| Abstract: | Based on miscible flooding well test analysis theory with carbon dioxide injection,the diffusion model of mixture components when carbon dioxide miscible with the oil and variation law of the temperature and viscosity are analyzed,and the influence of sudden changes the components and temperature(viscosity mutation) on pressure are studied,and the pressure changes into the pressure drop obtained by solving the compound well test model of two areas and the additional pressure drop caused by sudden drop of te... |
