| description | The invention discloses a preparation method of an artificial core in a petroleum geology research. The preparation method comprises the following steps: during the process of cementing quartz sand and epoxy resin through a cementing agent, introducing a nano porous material and a metal thin sheet, performing curing under pressure, soaking a core in acid or alkali or leaching the core to form slits, finally flushing the artificial core with distilled water, and drying. By the adding of polyethylene glycol and citric acid, the artificial core has high surface wettability, and the surface property is closer to natural core. According to the preparation method, the slits, micron-level pores and nano-level pores of the artificial core can be quantitatively controlled, so that the prepared artificial core is extremely high in similarity with the natural core and can meet simulation and test on such physical properties as sound wave, transfusion and conductivity of the core in the petroleum geology research, thus p |
