摘　　要：油田伴生气和CO_(2)驱采气的数量巨大,且其中含有较多的CO_(2),合理回收利用其中的CO_(2)是当前油田开发和气体资源利用的重要研究领域。回收其中的CO_(2)不仅响应国家环境保护政策,而且将其合理的资源化以提高经济效益。本文以油田伴生气、CO_(2)驱采气的CO_(2)回收技术为研究对象,详细介绍了当前五大类分离提纯工艺的基本原理,并对各工艺的特点以及实用性进行了综合对比与分析。另外总结分析了四类复合方法的适用性,得出变压吸附法+化学吸收法适用于较低CO_(2)浓度含量油田伴生气烃类回收和CO_(2)除杂;膜分离+变压吸附法以及膜分离+化学吸收法适用于CO_(2)浓度较高的CO_(2)驱采气的收集;化学吸收法+低温精馏法适用于制作高纯度的CO_(2)产品气。The quantity of associated gas and CO_(2) driven gas in oilfield is huge and contains a large amount of CO_(2),so the reasonable recovery and utilization of CO_(2) is an important research field in oilfield development and gas resource utilization.Recycling CO_(2) not only responds to the national environmental protection policy,but also improves the economic efficiency by rational resource utilization.This paper takes the CO_(2) recovery technology of associated gas and CO_(2) driven gas from oilfield as the research object,introduces in detail the basic principles of the current five types of separation and purification processes,and compares and analyses the characteristics and practicality of each process.In addition,the applicability of four types of composite methods is summarized and analyzed,and it is concluded that the variable pressure adsorption method+chemical absorption method is suitable for the recovery of hydrocarbons and CO_(2) decontamination of the associated gas of oilfield with low CO_(2) concentration;the membrane separation+variable pressure adsorption method and the membrane separation+chemical absorption method are suitable for the collection of CO_(2)driven gas with high CO_(2) concentration;and the chemical absorption method+low-temperature distillation method is suitable for the production of high-purity CO_(2) product gas.
