The invention belongs to the technical field of rock-like material test pieces, and particularly relates to a CO2 salt water layer geological storage test sandstone similar material and a preparation method thereof. The CO2 salt water layer geological storage model test sandstone similar material comprises the following components in parts by weight: 2-8 parts of quartz sand with the particle size of 40-50 meshes, 1-8 parts of quartz sand with the particle size of 100-200 meshes, 1-8 parts of quartz sand with the particle size of 1000-1250 meshes, 1-5 parts of cement, 1-2 parts of gypsum and 1-5 parts of water. Based on the physical and mechanical properties and microcosmic characteristics of protolith, a method for regulating and controlling the properties of the material by using aggregate is adopted, quartz sand is selected to improve the brittleness of the material, and gypsum and cement are selected as cementing materials to improve the strength of the material. The brittleness and strength of the sandstone-like material are realized, and the main physical mechanics of the similar material and the primary rock meet the similarity theory. The characteristics of the sandstone in the Shandong Dezhou diving sand river street group are successfully simulated. The invention has the advantages of few types of required materials, low cost, high manufacturing efficiency and wide practicability.
本发明属于类岩石材料试件技术领域，具体涉及一种CO2咸水层地质封存试验砂岩相似材料及制备方法。CO2咸水层地质封存模型试验砂岩相似材料以重量份计包括40‑50目粒径石英砂2‑8份、100‑200目粒径石英砂1‑8份、1000‑1250目粒径石英砂1‑8份、水泥1‑5份、石膏1‑2份和水1‑5份。基于原岩的物理力学性质以及细观特征，采用以骨料调控材料性质的方法，选用石英砂以提高材料的脆性，选用石膏和水泥作为胶结材料，提高材料的强度。实现了类砂岩材料的脆性和强度，相似材料与原岩主要的物理力学满足相似理论。成功的模拟了山东德州潜凹陷沙河街组中砂岩的特征。本发明所需材料种类少，成本低，制作效率高，具有广泛的实用性。
