Interlayer type-considered continental facies shale gas reservoir brittleness evaluation method

The invention relates to the technical field of measurement, in particular to a continental facies shale gas reservoir brittleness evaluation method considering an interlayer type, which comprises the following steps: calculating an experimental static elastic parameter based on a conversion coefficient of dynamic and static elastic parameters to obtain the experimental static elastic parameter and an experimental elastic brittleness index; determining the mineral content based on the experimental elastic brittleness index and element logging, and determining the category of main brittle minerals and the importance degree of the brittle minerals on the brittleness index; determining the brittleness index of the mineral based on the category of the main brittle mineral and the importance degree of the influence of the brittle mineral on the brittleness index; constructing an optimal comprehensive brittleness index model based on the elastic brittleness index and the mineral brittleness index; and carrying out
