CO_2地质储存潜力与适宜性评价方法及初步评价

A study of CO2 geological storage potential and suitability assessment

摘要: 借鉴国外CO2地质储存潜力与适宜性调查评价工作程序,在充分考虑我国复杂的地质背景、CO2地质储存研究现状等因素的基础上,将我国CO2地质储存潜力与适宜性评价工作划分国家级潜力评价阶段、盆地级潜力评价阶段、目标区级潜力评价阶段、场地级评价阶段、灌注、监测运行期评价阶段,按评价精度由低到高,分称为CO2地质储存潜力与适宜性评价E、D、C、B、A级;并对我国CO2地质储存潜力与适宜性进行了E级评价,即运用层次分析-模糊指数法对我国陆相沉积盆地进行了初步筛选,并对其储量进行了计算,认为我国陆上沉积盆地深部咸水含水层是最主要的CO2地质储量场所。

Abstract: Learning from geological investigation and assessment working procedures of foreign CO2 storage potential and suitability and taking our country’s complex geological background into account,CO2 geological storage potential and suitability assessment can be divided into national predicted potential assessment,basin presumed potential assessment,target controlled potential assessment,site based potential assessment and perfusion project potential assessment.According to the evaluation precision,fr...
