Abstract: CCUS is the key technology to achieve the carbon nautral target, and it is also the bottom technology to realize the large-scale low carbon utilization of fossil fuels. Monitoring can predict and discover CO₂ leakage in the CCUS project. Scientific and effective monitoring point deployment is not only directly related to the effectiveness and economy of field leakage monitoring in oil displacement and storage, but also of great significance for the safety evaluation of the project. Monitoring data can provide data support for the quantification and verification of carbon storage in the later stage of CCUS project. In view of the fact that there is no specific standard and specification for the deployment of leakage monitoring points for CCUS projects at home and abroad, the particularity of leakage monitoring in CCUS projects compared with conventional environmental monitoring is elaborated in detail. The deployment methods of leakage monitoring points for CCUS projects at home and abroad, such as Weyburn and Aquistore CCS in Canada, Teapot Dome project in Wyoming, and CCS projects in Shenhua, Shengli Oilfield, Daqing Oilfield and Yanchang Petroleum, are listed and analyzed in depth. It is concluded that: ①due to geological, well engineering and long-time span and other reasons, the leakage path presents the characteristics of “multi-point, wide-area and vertical three-dimensional”. In addition, there is no authoritative standard to guide monitoring at present. As a result, the deployment of CO₂ leakage monitoring points is one of the difficulties in the implementation of CCUS project monitoring. ②There are two main core strategies of CCUS project CO₂ leakage monitoring point deployment methods at home and abroad, namely risk-oriented hierarchical point deployment method and characteristic zoning classification method, each of which has its own advantages. Based on the current situation, this paper puts forward suggestions on the deployment of leakage monitoring points in CCUS projects, that is, a leakage monitoring point deployment strategy based on risk level differentiation and three-dimensionalization, aiming to provide case support and practical guidance for domestic CCUS projects to build an efficient, accurate and low-cost monitoring network.
