【摘要】 文章系统收集并分析了我国各盆地地层、大地构造、油田地质、水文地质数据,研究了我国各盆地碳酸盐岩地层空间分布和孔隙度特性,做出了《全国盆地碳酸盐岩分布面积分级图》、《全国盆地碳酸盐岩厚度分级图》、《全国盆地碳酸盐岩孔隙度分级图》、《全国盆地碳酸盐岩二氧化碳地质储存潜力分级图》。逐一对全国各沉积盆地内800~5 000m深度区间各地质时代形成的碳酸盐岩储层的CO2储存能力进行了计算。通过层次分析法确定各评价指标权重,制做出全国盆地E级碳酸盐岩储层CO2地质储存适宜性评价结果表,绘制出《全国盆地碳酸盐岩储层CO2储存适应性评价图》。对全国盆地CO2储存进行了适宜性评价,剔除了不适宜CO2地质储存的沉积盆地,选出适宜的沉积盆地以供下一阶段继续研究。更多还原

【Abstract】 Geological storage of carbon dioxide is one of the effective techniques to reduce CO2 emissions.Evaluation of capacity and suitability of such storage can provide a scientific foundation for policies of reducing greenhouse gas emissions.This work collects and analyzes the relevant data from the studies of petroleum geologyand engineering and hydrogeology.The porosity and thickness of carbonate formations in the basins of China mainland are investigated.A series of important geological maps related to CO2 storage in carbonate formations in these basins are prepared,including the"Classification map of areas of carbonate formations in the basins of China","Classification map of thicknesses of carbonate formations in the basins of China","Classification map of porosities of carbonate formations in the basins of China","Classification map of CO2 storage capacity of carbonate formations in the basins of China","Classification map of suitability of CO2 storage in carbonate formations in the basins of China".After suitability evaluation and removal of those basins not suitable for CO2 storage,the basins with high suitability for CO2 storage are chosen for further investigation.更多还原
