摘　　要：本文在充分调研CO_(2)注气吞吐适应性的基础上,针对薄互层油藏的成藏特征,运用模糊层次分析法,对区块内所有采油井进行注气适应性定量评价,优选适宜CO_(2)吞吐的意向井进行数值模拟,结果表明,CO_(2)吞吐可以在短期内大幅提高油井产量,是薄互层油藏提高采收率的有效手段。This paper uses fuzzy analytic hierarchy process to quantitatively evaluate the gas injection adaptability of all oil production wells in the block according to the accumulation characteristics of thin interbedded oil reservoirs,and preferably suitable for CO_(2)injection Numerical simulations of the intentional wells in,the results show that CO_(2)injection can greatly increase the production of oil wells in a short period,and it is an effective means to improve the oil recovery of thin interbedded oil reservoirs.
