Abstract

CO₂ huff and puff is a widely used enhanced oil recovery method in many oil fields, but its implementations in shale fields is scarce. This paper reports trials of CO₂ huff and puff in a shale field in China. Laboratory studies revealed that CO₂ effectively reduced oil viscosity, increased oil volume, and improved oil recovery under miscible conditions. For the three wells that received CO₂ huff and puff treatments, one well showed satisfactory results, while the other two wells demonstrated poor economics. Discussions and recommendations are made based on field experiences. © 2024 Society of Chemical Industry and John Wiley & Sons, Ltd.

页岩油田二氧化碳呼哧法现场试验

二氧化碳吹浮法是一种在许多油田广泛应用的提高采收率方法，但在页岩油田的应用却很少。本文报告了在中国某页岩油田进行的二氧化碳气浮试验。实验室研究表明，在混溶条件下，二氧化碳能有效降低石油粘度，增加油量，提高石油采收率。在三口接受了二氧化碳膨化处理的油井中，一口油井的效果令人满意，而另外两口油井的经济性较差。根据现场经验进行了讨论并提出了建议。© 2024 化学工业协会和约翰-威利父子有限公司版权所有。

期刊介绍： Greenhouse Gases: Science and Technology is a new online-only scientific journal dedicated to the management of greenhouse gases. The journal will focus on methods for carbon capture and storage (CCS), as well as utilization of carbon dioxide (CO2) as a feedstock for fuels and chemicals. GHG will also provide insight into strategies to mitigate emissions of other greenhouse gases. Significant advances will be explored in critical reviews, commentary articles and short communications of broad interest. In addition, the journal will offer analyses of relevant economic and political issues, industry developments and case studies. Greenhouse Gases: Science and Technology is an exciting new online-only journal published as a co-operative venture of the SCI (Society of Chemical Industry) and John Wiley & Sons, Ltd
