Method of classification characterization of rock inorganic-mineral pores

The invention belongs to the technical field of petroleum and natural-gas geological-exploration, specifically provides a method of classification characterization of rock inorganic-mineral pores, andaims to solve the problem that existing characterization methods cannot carry out classification and quantification characterization on pores of development of different inorganic mineral. The methodof the invention comprises the steps of: obtaining an electron microscope scanning image of a rock sample in a test view field; determining inorganic mineral contained in the sample in the test viewfield, and obtaining a mineral surface distribution image of all the inorganic mineral; and superimposing the electron microscope scanning image and the mineral surface distribution image, and obtaining overall pore information in the test view field and intragranular pore information and intergranular pore information of development of the different inorganic mineral. The method of the inventioncarries out classification c
