The application discloses a method for strengthening basalt carbon sequestration and application thereof, and belongs to the field of novel carbon sequestration technology. The application introduces a mixture of pyrolytic carbon and hydrothermal carbon to treat basalt particles, utilizes the characteristics of abundant pore structure and oxygen-containing functional groups of biochar, especially the role of the biochar as an electron donor, promotes the reduction and conversion of Fe (III) on the surface of basalt to Fe (II), thereby effectively inhibiting or destroying the iron-based passivation layer which hinders the weathering reaction; meanwhile, the local supersaturation is reduced by adsorbing and chelating Ca 2+ , Mg 2+ and the like, so that the dissolution reaction is continuously driven. Experiments show that the method can significantly improve the corrosion current density and dissolution rate of basalt in water phase, and greatly enhance the carbon capture and storage capacity of carbon dioxide in air. The application has the advantages of low cost, environmental friendliness, significant carbon sequestration and efficiency enhancement, and is suitable for farmland soil improvement and large-scale rock weathering carbon sequestration engineering.

The application discloses a kind of electrical parameter calculation methods of orthometamorphic rock weathering crust, comprising: reading the conventional logging curve data of the depth corresponding to orthometamorphic rock weathering alteration index;Logging curve data and orthometamorphic rock weathering alteration index data are fitted into linear relationship chart;According to the correlation of the linear relationship chart of fitting, select the logging curve with high sensitivity of orthometamorphic rock weathering crust identification;The logging curve data with high sensitivity of orthometamorphic rock weathering crust identification is normalized;Fitting orthometamorphic rock weathering crust electrical parameter calculation formula;The logging curve data after normalization is brought into orthometamorphic rock weathering crust electrical parameter calculation formula.The present application is based on the analysis of a large amount of logging curve data, establishes a new orthometamorphic rock weathering crust electrical parameter calculation model, and proposes a new method for identifying orthometamorphic rock weathering crust.
