  • Artificial sandstone and/or conglomerate core based on lithology and pore structure control and preparation method and application thereof
    Patent number: 11192824
    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 pore structure control. The method comprises the following steps: mixing and molding sand particles and a inorganic cementing agent in sequence, and further adding a curing agent for performing solidification to prepare an artificial sandstone and/or conglomerate core; wherein composition of the sand particles is determined according to lithology and pore structure of the artificial sandstone and/or conglomerate core. The present disclosure combines the lithology and the pore structure of the artificial sandstone and/or conglomerate core with the composition of the sand particles, particularly regulates and controls the composition of the sand particles according to the pore throat distribution pattern and the average pore throat radius, thereby performing precise control on the artificial sandstone and/or conglomerate core.
    Type: Grant

  • Artificial sandstone and/or conglomerate core based on lithology and permeability control and preparation method and application thereof
    Patent number: 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.
