Silicate high-porosity artificial rock core and preparation method thereof
The invention discloses a silicate high-porosity artificial rock core and a preparation method thereof. The preparation method specifically comprises: mixing polymer dispersion liquid and a water glass solution according to the mass ratio of 1: 1, heating to 40-50 DEG C and left to stand for 4-6 h, and forming gel; cooling the gel to-50 DEG C, and freezing the gel into ice cubes; drying the ice cubes in vacuum to obtain a hard spongy solid; and heating the hard spongy solid to 500-600 DEG C, and keeping the temperature constant for 2 hours to obtain an artificial rock block, namely the silicate high-porosity artificial rock core. The size of pores in the rock core produced by the method is close to that of pores in a natural rock core, but the number of pores existing in unit volume is larger than that of pores existing in the natural rock core, so that the phenomena of passing, adsorption and the like of foreign substances in the pores can be conveniently and quickly observed.
本发明公开了一种硅酸盐高孔隙度人造岩心及其制备方法，具体的制备方法为：将聚合物分散液和水玻璃溶液按照质量比为1:1的比例混合，升温至40‑50℃，静置4‑6h，形成凝胶状物；将凝胶状物降温至‑50℃，冻结成冰块；将冰块真空干燥，得硬海绵状固体；将硬海绵状固体升温至500‑600℃，恒温2h，得人造岩石块，即一种硅酸盐高孔隙度人造岩心。本发明产生的岩心中孔隙大小和天然岩心中的孔隙大小接近，但在单位体积内存在的孔隙数量要比天然岩心要更多，便于快速观察外来物质在孔隙中的通过、吸附等现象。
