In this paper, we take the C oil field as an example, and adopt the combination well spacing of vertical and horizontal wells to establish a geologic model, then discuss the exploitation effect of CO₂ displacement under five different permeability levels and eight different row spacing distributions. Finally, we deeply analyze the economic benefit of CO₂ displacement under different oil prices with the help of economic evaluation criteria. Through the above research, we obtain the following conclusions: When the permeability is between 0.1×10^-3 μm² and 1×10^-3 μm², the C oil company should choose the CO₂ displacement exploitation rather than waterflooding under the current oil price; although decreasing the row spacing will enhance oil recovery, it will decrease the economic benefit, so the C oil company should adopt the appropriate row spacing according to their own current situation; prolonging the productive life will increase the production rate of recovery, but that is no good to the economic benefit, so the C oil company should choose the appropriate productive life by self-condition., authors=LIN Lijun¹, YANG Zhengming², WANG Xuewu², HE Ying², LIAO Zuocai³, authorsList=LIN Lijun, YANG Zhengming, WANG Xuewu, HE Ying, LIAO Zuocai, authorCompany=1.
