Abstract
A preparation method of a micro-nanofluidic model of triple-medium carbonate reservoir includes the following steps: obtaining a cave structure, a fracture structure and a pore structure of a carbonate rock, and preparing a first mask, a second mask and a third mask respectively; forming a photoresist layer on a glass substrate, and subjecting the photoresist layer to an exposure treatment and an etching treatment through the first mask, the second mask and the third mask sequentially, and then subjecting to a washing treatment, to obtain a first intermediate model; fitting the etched side of the first intermediate model with a glass cover, and subjecting to a bonding treatment, to obtain a second intermediate model; introducing a first solution, a second solution and a third solution into the second intermediate model sequentially to form a calcium carbonate nanocrystalline layer and to obtain the micro-nanofluidic model of triple-medium carbonate reservoir.
