METHOD AND DEVICE FOR PREPARING ARTIFICIAL CORE FOR PETROLEUM GEOLOGICAL EXPLORATION
The present disclosure provides a method and device for preparing an artificial core for petroleum geological exploration. The method includes: step 1, establishing a relation curve between a median grain diameter of quartz sand and a permeability, determining a type and a usage amount of epoxy resin, and preparing a cementing agent according to a principle that the epoxy resin has a direct ratio with a specific surface; step 2, based on a method of controlling a core permeability, preparing benchmark sand with quartz sand of different grain sizes in a certain ratio, fabricating a low-permeability core by adjusting a ratio of the benchmark sand to fine sand, and fabricating a high-permeability core by adjusting a ratio of the benchmark sand to coarse sand; step 3, separately and proportionally weighing quartz sand of different grain diameters and putting them into a magnetic tray, manually mixing and agitating for later use.
