    Abstract
  • Different from the mechanism of improving light oil recovery by CO2 injection, heavy oil does not mix with CO2, so the main factors affecting its development are very different. Especially in the process of thermochemical composite oil recovery, the injected CO2 mainly plays a role in insulating heat, reducing viscosity and increasing energy. The properties of heavy oil were determined in this study in order to systematically investigate the effects of different factors influencing CO2 displacement. The effect of heavy oil viscosity, temperature, pressure and permeability on recovery were investigated using the orthogonal experimental method. Temperature was the most significant factor, followed by permeability, pressure and heavy oil viscosity. According to the experimental results and considering factors such as reservoir temperature and permeability, the field tests of CO2 huff and puff in the Shengli Oilfield of SINOPEC were conducted. Production results show that increasing reservoir temperature and permeability is beneficial for CO2 EOR and can improve oil production.
