摘要: CO2吞吐工艺是一种可应用于常规与非常规油藏的有效提高采收率技术。从室内实验研究到重点领域的应用实践方面总结了CO2吞吐技术应用进展,对不同技术路线的现场试验进行了回顾与分析。应用结果表明:CO2吞吐技术对不同油品、不同类型的油藏都有广泛的适用性,在国内外矿场应用中均取得了良好效果;CO2复合吞吐、CO2协同吞吐、超临界CO2吞吐、纳米颗粒辅助CO2吞吐技术将是未来的主要发展方向,其中,超临界CO2吞吐和纳米颗粒辅助CO2吞吐技术目前仍然局限于实验室阶段,还需进一步研究并通过矿场应用证实其实用性。在2060年前实现碳中和的背景下,CO2吞吐技术应用规模将进一步扩大,该研究也将对CO2吞吐技术的推广应用提供技术支持。

Abstract: CO2 stimulation technology is effective in enhanced oil recovery conventional and unconventional oil reservoirs. The advances in the application of CO2 stimulation technology was summarized from in-house laboratory investigation to application and practice in key fields, and the field tests with different technical routes were reviewed and analyzed. The application results indicated that with wide application range in different oil products and different reservoirs, CO2 stimulation technology achieved good results in the mines at home and abroad. The reservoirs will be developed with the technologies of CO2 composite stimulation, CO2 synergistic stimulation, and supercritical CO2 stimulation and nanoparticle-assisted CO2 stimulation in the future. Supercritical CO2 stimulation and nanoparticle-assisted CO2 stimulation are still under the laboratory experiment. Their practicability should be further studied and verified by field application. In the context of achieving the target of carbon neutralization by 2060, the application scale of CO2 stimulation technology will be further expanded. This study will also provide technical support for the promotion and application of CO2 stimulation technology.
