CO2气体注入是一种推荐的提高原油采收率（EOR）方法，它是在达到残余饱和度后通过储层孔隙注入CO2，因为CO2容易溶解在油相中，这一点已被许多其他研究人员在相关的现场研究中证实。CO2-EOR研究迫切需要一个涵盖地质、物理、油藏、生产、工艺和经济等多学科的综合评价体系。因此，这些系统必须是可靠的，建议最终决定的可行性CO2-EOR操作程序，适用于中试规模或全规模。本文提出了一种综合系统评价，它具有以下特点：（1）估计溶解的CO2的分数，（2）估计粘度降低，（3）估计所得到的未来石油生产率指数，（4）预测增加的石油生产，（5）估计地面设施设备设计，（6）评价经济方面和（7）产生CO2-EOR操作方案的可行性的最终决策。最后，作为本项目的主要目标，这些系统将呈现我们需要促进或拒绝CO2-EOR计划方案的基本原因的画面，并且还将呈现一些建议，如果CO2-EOR计划没有按照预期执行。
CO2gas injection is one of the recommended enhanced oil recovery (EOR) methods by injecting CO2through reservoir pores after the residual saturation is reached, since CO2dissolves easily in oil phase as confirmed by many other researchers in pertaining field studies. An integrated system is urgently required for assessing CO2-EOR study, covering multi-disciplinary aspects as follows: geology, geophysics, reservoir, production, process and economic. Hence, those systems must be reliable in suggesting final decision for feasibility of CO2-EOR operation program, applicable either for pilot scale or for full scale. This paper is proposing an integrated system evaluation, which has the following features: (1) estimate fraction of dissolved CO2, (2) estimate viscosity reduction, (3) estimate future oil productivity index resulted, (4) forecast incremental oil production, (5) estimate surface facilities equipment design, (6) evaluate economical aspects and (7) generate final decision for feasibility of CO2-EOR operation program. Finally, as the main objective of this program, those systems will present a picture of essential reason why we need to promote or reject CO2-EOR plan program, and also some recommendations will be presented in case the CO2-EOR plan does not perform as expected.
