Abstract:

Carbon Capture,Utilization and Storage (CCUS) technology is an important tool for the energy sector to enable efficient oil and gas production under the dual-carbon goal. Injecting CO2 into oil reservoirs can significantly enhance oil recovery. However,its mobility differs greatly from that of the crude oil,and there’s clear differentiation with oil and water,which results in a limited sweep efficiency of CO2. Therefore,it is urgent to develop efficient CO2 plugging materials and corresponding plugging control technologies to improve reservoir recovery and CO2 storage efficiency. This article explains the characteristics of plugging in the CO2 flooding process and gives an overview of the commonly used CO2 plugging materials and methods. It also describes their applications in oil fields across the world,and their potential for improving CO2 recovery and storage in Xinjiang Oilfield. This study is inspiring for the global research and development of plugging materials in the process of CO2 flooding in oilfields worldwide,and highlights the future direction of CO2 plugging technology in Xinjiang oilfields.

摘要:

碳捕集、利用与埋存技术(CCUS)是目前能源领域在双碳目标下实现油气高效开采的重要手段。将CO2注入油藏中可提高采收率,但其流度与原油差异大且与油水存在明显的分异作用,导致波及效率有限。急需研发高效的CO2封窜材料及相应的控窜技术,以提高油藏采收率和CO2封存效率。介绍了CO2驱过程中的窜逸特征,综述了目前常用的CO2封窜材料与方法。展示了各项CO2封窜技术在国内外油田的应用现状,并展望了在新疆油田CO2提高采收率与储存过程中可能的应用前景。本研究对当前国内外油田CO2驱过程中的封窜材料研发有一定的启示,指出了新疆油田CO2封窜技术的发展方向。
