摘　　要：CO2驱油是以液体CO2为驱油剂,利用其与原油混相后原油黏度降低、原油体积膨胀等特性来提高原油采收率的技术。目前,我国CO2驱油尚处于先导试验阶段,还未进入大规模工业应用阶段。中国石化草舍油田实施了CO2驱油提高采收率先导试验项目,取得了良好的经济效益。根据草舍油田CO2驱油提高采收率项目,阐述了CO2驱原料气净化工艺、成品CO2输送工艺、CO2压注工艺及CO2驱产出气回收利用等技术,对国内同类项目的开展具有一定的借鉴意义。Carbon dioxide flooding is a technology that takes carbon dioxide as oil displacement agent to enhance oil recovery with its properties of reducing crude viscosity and expanding its volume when mixed with it. At present, carbon dioxide flooding in China is in the experimental stage, and has not been in the stage of large-scale industrial application. The experimental project of carbon dioxide flooding to enhance oil recovery was implemented with good economic benefits in Caoshe oilfield. Based on the project, feed gas purifying process, product carbon dioxide transportation process, carbon dioxide injection process and output gas recycle technology were expounded, which could be used for reference to other projects of this kind.
