Effects of heat,viscosity reducer and gas on viscosity of crude oil in thermal composite flooding
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 tem-perature is the most effective way to reduce the viscosity of crude oil.In a certain pressure range,N2 is disadvantageous to reduce the viscosity of crude oil,and CO2 is advantageous to reduce the viscosity of crude oil.The viscosity reducer and CO2 can synergistically reduce the viscosity of crude oil.
