摘　　要：为了研究热、降黏剂、气体单独对原油黏度影响,以黏度、降黏率为指标,通过高温高压流变仪研究了复合驱中热、降黏剂、气体对原油黏度的影响规律。结果表明,升高温度是降低原油黏度的最有效方式,在一定压力范围内,N2对降低原油黏度起负作用,CO_(2)对降低原油黏度起正作用,降黏剂与CO_(2)可协同作用降低原油黏度。In order to study the effects of heat,viscosity reducing agent and gas on the viscosity of crude oil,the effects of heat,viscosity reducing agent and gas on the viscosity of crude oil in composite flooding were studied by using high temperature and high pressure rheometer.The results show that increasing temperature is the most effective way to reduce the viscosity of crude oil.In a certain pressure range,N_(2) is disadvantageous to reduce the viscosity of crude oil,and CO_(2) is advantageous to reduce the viscosity of crude oil.The viscosity reducer and CO_(2) can synergistically reduce the viscosity of crude oil.
