Patent ID: 11136265

Abstract:
The present disclosure relates to the technical field of artificial cores, in particular to a preparation method of artificial sandstone and/or conglomerate core based on lithology and permeability control. The method comprises the following steps: mixing and molding sand particles and a cementing agent in sequence, and further adding a curing agent for performing solidification to prepare the artificial sandstone and/or conglomerate core; wherein composition of the sand particles is determined according to properties of the artificial sandstone and/or conglomerate core comprising lithology and permeability. The present disclosure combines the properties of the artificial sandstone and/or conglomerate core with the proportion of the sand particles, particularly regulates and controls the composition of the sand particles according to the lithology and permeability of the artificial sandstone and/or conglomerate core, thereby performing precise control on the artificial sandstone and/or conglomerate core.
