Quantitative characterization method and device for physical phase of productivity rocks

The invention discloses a quantitative characterization method and device for physical phases of productivity rocks, and belongs to the technical field of oil-gas field development. The method comprises the steps: firstly, extracting production test data to establish a production data big table by taking a vertical well perforation or a horizontal well section cluster as a data unit, carrying out space grid conversion on productivity parameter characteristics by utilizing a grid technology, and calculating an overlapping degree coefficient between different geological and engineering characteristic parameters; and establishing a hierarchical structure between different geological and engineering characteristics by using a hierarchical clustering algorithm by taking a grid density overlapping degree as a key attribute, mining master control geological and engineering factors of productivity difference, and finally determining a productivity rock physical facies type according to a threshold value output result
