砂泥岩互层模型对CO2地质储存影响的数值模拟
Numerical Simulation on the Effect of Generalized Model of Sandstone and Mudstone Interlayers on CO2 Geological Storage
摘要
Abstract
Multiple generalized models of different sandstone and mudstone interlayers were built and numerical simulations were carried out to estimate CO2 injectivity,migration and containment in deep saline formations under different sandstone and mudstone interlayers by taking the borehole data from Jiangling Depression for instance.Simulations results show that the sandstone and mudstone interlayers significantly influences CO2 injectivity, migration and containment. CO2 injection amount decreases with more and thinner sandstone and mudstone interlayers;however,more and thinner sandstone and mudstone in￣terlayers could effectively prevent the upward and horizontal migration of CO2 plume and improve space use efficiency. CO2 containment decreases with more and thinner sandstone and mudstone interlayers. Since the thinner mudstone interlayer is difficult to be an inde￣pendent caprock,a thick mudstone caprock is needed to ensure the long￣term security of CO2 geological storage.What’s more,from the aspects of injectivity,migration and contain￣ment,it is advisable to adopt the generalized model of multiple sandstone and mudstone in￣terlayers to approximately represent the actual stratigraphy model to carry out the early suitability assessment of CO2 geological storage.关键词
