摘　　要：根据实际深层油藏高温高压条件,设计了一套高温高压流体驱替微观可视化实验系统。根据岩石内部孔喉特征,制作相匹配的可视化微纳米尺度孔喉模型,通过温压协调控制系统及驱替反应系统,实现了高温高压条件下流体在微纳米通道中的流动,结合微观图像采集系统观察多孔介质内微观流体运移特征。该系统为油田储层开发过程中的油气水饱和度分布的定量描述和不同驱油方式的筛选提供了重要实验依据。该套实验设计克服了常规实验无法进行高温高压驱替的缺点,且具有可重复性、准确性,有利于激发学生创新意识和自主设计实验的积极性,培养学生解决实际工程问题的能力。According to the actual high temperature and high pressure conditions of deep reservoirs,a set of microscopic visualization experimental system of high temperature and high pressure fluid displacement is designed.The matching visual micro-nano scale pore throat model is made according to the characteristics of pore throat structures inside the rock.Through the temperature and pressure coordination control system and displacement reaction system,the fluid flow in micro nano channel under high temperature and high pressure conditions is realized.The characteristics of microscopic fluid migration in porous media can be observed combined with microscopic image acquisition system.The system provides an important experimental basis for the quantitative description of oil,gas,and water saturation distributions and the selection of different oil displacement methods in the process of oilfield reservoir development.This set of experimental design overcomes the disadvantage that conventional experiments can not carry out high temperature and high pressure displacement,and the experiments are repeatable and accurate.It is beneficial to stimulate students'innovation consciousness and initiative of designing experiments independently,and cultivate students'ability to solve practical engineering problems.
