Investigations and potential assessment of basalt CO2 mineral sequestration experiment field:A case study of Tianyangvolcanic fault basin in Leizhou peninsula,China
摘要
Abstract
Porous basalt is rich in iron and magnesium,and has better mineral capture ability compared to sandstone.It can quickly and efficiently convert carbon dioxide(CO2)into solid carbonate minerals.Basalt CO2 mineral sequestration has become anemerged as a new type of carbon capture and storage(CCS)technology that has attracted much attention.Basalt is widely distributed around the globe,but research and demonstration projects on basalt CO2 mineral sequestration technology have not yet been initiated in China.The discovery of large-scale Quaternary basalt in the Leizhou Peninsula presents a promising opportunity to establish a valuable natural laboratory for CO2 mineral sequestration research.This study conducted comprehensive geophysical exploration at alternative sites,combining geological outcrops,drilling cores,and rock physics data to analyze the distribution and physical parameter characteristics of basalt.The study applied comprehensive geophysical seismic and electromagnetic exploration to analyze the strata and structure of Tianyang Mar Lake,combined with drilling data and magnetic exploration results,further confirming the existence of Mar Lake type basalt strata underground in Tianyang.Large scale basalt was developed from shallow to deep layers,with great potential for mineralization and storage.The stratigraphic structure of basalt in Tianyang area was studied and calculated,and it was found that the basalt had good stratigraphic continuity and great potential for CO2 mineralization and storage.According to the calculation formula,the theoretical storage capacity of basalt in the study area was estimated to be 11.037 6 Gt.The research results not only provided important physical parameters for the mineralization and CO2 storage experiments of basalt,but also provided important support for the site selection and injection design of CO2 storage experiments of basalt in LeizhouPeninsula.关键词
