摘要：

采用轴对称悬滴形状分析技术研究了高温、高压条件下CO₂-原油体系和原油-碳酸水体系的相间作用及其界面张力的变化规律。研究结果表明：在高温、高压条件下CO₂与原油之间的相间作用可分为2个阶段，第1阶段为CO₂溶解并使原油膨胀，第2阶段为CO₂抽提轻质组分并使油相体积减小；压力增大，CO₂与原油的相间作用速度变快，压力接近最小混相压力时，油滴形态变得极不稳定，CO₂对轻质组分的抽提作用增强，CO₂与原油界面变模糊。温度和压力是影响CO₂与原油界面张力的主要因素，温度越高，气液界面越不稳定，动态界面张力波动越大，平衡界面张力越大；压力越高，动态界面张力达到平衡时间越短，最终的平衡界面张力越低。原油-碳酸水体系界面处的相互作用较弱，油水界面清晰，油滴形态稳定。CO₂从水相向油相逐渐扩散过程中，油滴体积不断膨胀并逐渐达到稳定，未出现CO₂抽提轻质组分导致油滴体积减小的现象。随着CO₂在水相中的溶解及向油相中的扩散，界面张力逐渐下降并达到平衡；温度和压力越高，油水界面张力达到平衡的时间越短，油水界面张力越小。

Abstract:

The axisymmetric drop shape analysis technology was used to study the phase interactions of CO₂-oil system and oil-carbonic water system as well as the interfacial tension (IFT) change laws at high temperature and high pressure. The results indicate that the phase interaction between CO₂ and crude oil at high temperature and high pressure can be divided into two stages. The first stage refers to the CO₂ dissolution resulting in oil swelling, and the second stage refers to the extraction of light components by CO₂ resulting in a shrinkage in oil-phase volume. In case of higher pressure, the phase interaction between CO₂ and crude oil becomes faster. Under the minimum miscible pressure, the shape of oil droplet becomes very unstable, the extraction of light components by CO₂ is enhanced and the interface between CO₂ and crude oil becomes blurred. The temperature and pressure are the main factors that affect the IFT of CO₂ and crude oil. The higher the temperature is, the less stable the gas-liquid interface will be, the higher the dynamic IFT fluctuation will be, and the larger the equilibrium IFT will be. The higher the pressure is, the shorter the equilibrium time of dynamic IFT will be, and the lower the final equilibrium IFT will be. In the oil-carbonic water system, the phase interaction is weak with clear oil-water interface and stable oil droplet shape. When CO₂ is diffused into oil phase from water phase, the volume of oil droplet continues to increase and gradually achieves a stable state, and the extraction of light components by CO₂ resulting in shrinkage in oil droplet volume cannot be observed. When CO₂ is dissolved in water and diffused into oil phase, the IFT is gradually decreased to achieve equilibrium. Under the higher temperature and pressure, the equilibrium time for oil-water IFT will become shorter, and the oil-water IFT is smaller.

Key words: axisymmetric drop shape analysis, CO₂-crude oil system, oil-carbonic water system, interfacial tension, phase interaction
