摘要：

CO2 flooding process has been a proven valuable tertiary enhanced oil recovery (EOR) technique. Meanwhile, it can also store greenhouse gas like CO2. However, in the late period of CO2 flooding process, mixed gases containing CO2 and hydrocarbon gases would be produced along with the production of crude oil. Usually, these mixed gases would be separated by gas processing plant. To prevent greenhouse effect, CO2 is re-injected to the reservoir while hydrocarbon gas is sold in the market. But the separation process is very costly. In this article, the feasibility of the produced gas re-injection without separation was investigated by experiment. Based on the produced oil and gas of Jilin oilfield, slim tube tests were conducted to study displacement efficiency of the crude oil by CO2 re-injection. In addition, components of the produced oil were analyzed according to the color and production stages. Finally, factors like displacement pressure and CO2 content were studied. It was found that produced gas re-injection without separation is a feasible method to save time and cost.
