Abstract: The present invention belongs to the technical field of petroleum and natural gas exploration and development, and specifically relates to a study method for chlorite growth pattern based on an in-situ high-precision observation means. The method includes: S1: selecting a sample and quantitatively characterizing mineral components; S11: selecting a typical sandstone sample developed with a chlorite coating and cement, grinding a rock slice, and observing under a microscope and a scanning electron microscope to determine a basic morphological characteristic, occurrence state and type of the chlorite; S2: performing data preprocessing on the sample; S3: establishing a water-rock numerical simulation model; S4: developing a water-rock numerical simulation experiment; S5: analyzing a water-rock numerical simulation result; and S6: explaining and applying the water-rock numerical simulation result.
