An evaluation method for different types of pore evolution in shale is related, which is applied to the field of unconventional oil and gas research. As the shale depth or maturity increases, different types of pores (including intergranular pores, intragranular pores, organic pores and fractures) developed in shale are constantly changing, which is important for shale oil and gas accumulation. The present invention starts from the high-resolution scanning electron micrography of shale, and respectively extracts the areal porosity of different types of pores based on the division criteria of different types of pores and pore identification in the established shale, and combines the low-temperature N, COadsorption experiments and the high-pressure mercury intrusion experiments to obtain the total pore volume and establish the evolution chart of different types of pores. The proposed method has an important application value for the exploration of unconventional shale oil and gas resources.
