Discriminant analysis method for multi-stage genetic dense dolomite

The invention discloses a discriminant analysis method for multi-stage cause dense dolomite. The discriminant analysis method comprises the following steps: firstly, carrying out preliminary discrimination on the dense dolomite according to symbolic morphological characteristics of the dense dolomite; carrying out a pore permeability physical property test, and judging the compactness degree of the dolomite; researching a whole rock sample, microcell-surrounding rock properties, petrology and lithofacies characteristics, morphological characteristics of surrounding rock and cuttings, dolomite formation period, over-dolomization and de-dolomization characteristics; performing geochemistry and isotope environment characteristic analysis, finally performing rare earth element form testing on a target rock core, researching a partition mode and cause evolution characteristics of the target rock core, proposing a cause mechanism, determining similarities and differences of dolomite crystals in pores and dolomite c
