Abstract

Abstract:

In the later stage of heavy oil reservoir development by steam injection, the steam channeling is serious and the development effect gets worse year by year. So it is urgent to apply relevant technologies to improve steam flooding performance. According to the characteristics of the heavy oil reservoir in Z32 Qigu Formation in Fengcheng Oilfield, the feasibility of steam flooding assisted by CO₂ injection to improve the development effect has been studied. In the process of steam injection in heavy oil reservoir, the injection of CO₂, N₂ or flue gas can make crude oil swell, increase formation elastic energy, reduce viscosity of crude oil and improve oil flow capacity of crude. The swell and viscosity reduction effects of different types of injected gas on heavy oil have been measured by high temperature and high pressure crude oil sampler and core flow experiment device. The volume expansion of crude oil is about 10 % ~ 40 %, 2 % ~ 10 % and 4 % ~ 16 % by injecting CO₂, N₂ and simulated flue gas respectively, the viscosity is reduced by 27.3 % ~ 82.9 %, 4.3 % ~ 18.5 % and 10.2 % ~ 45.8 %, respectively, and the oil recovery is enhanced by 5.83 %, 3.08 % and 3.75 %, respectively. Therefore, CO₂ is recommended as the injection medium. Field application shows that after the new technology is implemented, the daily oil production of the well group increases from 26.6 t to 36.2 t, the oil steam ratio increases from 0.174 to 0.206, and the total oil production increases by 1 158 t. Remarkable economic benefits are obtained, which provides references for the scale application of this new technology.

Key words: heavy oil, CO₂, auxiliary steam drive, laboratory experiment, on-site application
