山东省二氧化碳地质封存研究现状及进展

Present Condition and Progress of Carbon Dioxide Geological Storage in Shandong Province

摘要:

为了进一步遏制全球气候变化，有效降低大气中的二氧化碳浓度，顺利完成双碳目标，我国陆续实施CCUS项目并逐步推进应用。近年来围绕地质碳封存研究，山东省自然资源厅部署实施了6项碳封存地质勘查项目，研究结果显示，山东省划分为深部咸水层、枯竭油气藏、不可采煤层及大型盐穴等4种碳封存地质类型，摸清了不同地质类型的储层、盖层条件和适宜性，明确了深部咸水层是未来碳封存主要潜力介质和发展方向。同时齐鲁石化胜利油田CCUS案例表明山东省的二氧化碳驱油技术已趋向成熟。山东省地质碳封存地勘项目研究及CCUS案例实施，为山东省“双碳目标”的顺利实现提供了地质理论和技术支撑。

Abstract:

In order to further curb global climate change, effectively reduce the concentration of carbon dioxide in the atmosphere, and successfully achieve the dual carbon goals, CCUS projects has been successively implemented and gradually promoted their application in China. In recent years, the Department of Natural Resources of Shandong Province has deployed and implemented six geological exploration projects for carbon sequestration research. As showed by the research results, Shandong province can be divided into four geological types of carbon sequestration, they are deep saline aquifers, depleted oil and gas reservoirs, unmineable coal seams and large salt caverns. The reservoir and cap rock conditions and suitability of different geological types have been identified,It is clarified that deep saline aquifers are main potential and development direction for carbon sequestration in the future. As showed by CCUS project of Qilu Petrochemical Shengli Oilfield, application of carbon dioxide flooding technology in Shandong province has become mature. The research on geological carbon sequestration geological exploration projects in Shandong province and the implementation of CCUS projects can provide geological theory and technical support for realizing "dual carbon goals" smoothly in Shandong province.
