| 摘 要： | 以江苏金坛盐岩地下油气储库为示范工程，以精铁粉、重晶石粉、石英砂、一级松香和医用酒精为原料，根据相似原理以及金坛盐岩油气储库地层中盐岩、泥岩和盐岩夹层的实测物理力学参数，开展了各种配比条件下材料的单轴压缩、三轴压缩、直剪和巴西劈裂试验，通过原岩和模型材料的重度、泊松比、弹性模量、抗压强度、抗拉强度、黏聚力、内摩擦角等基本物理力学参数以及相应变形特征和强度破坏特性的对比分析，研制出基本满足相似条件要求的盐岩油气储库介质（盐岩、泥岩和盐岩夹层）的地质力学模型相似材料，为开展盐岩地下油气储库运营的变形与失效破坏地质力学模型试验提供了可靠的材料保证。

| Abstract: | The Jintan oil-gas storage of salt rock in Jiangsu Province is a demonstration project; and the similitude material is made up of fine iron, barite powder, quartz sand, rosin and medical alcohol. According to principle of similitude and measured physico-mechanical parameters of salt rock, mudstone and salt rock interlayer of oil-gas storage of Jintan, the uniaxial compressive test, triaxial compressive test, direct shear test and Brazilian test under different material proportions are carried out. After comparing and analyzing the bulk density, Poisson’s ration, elastic modulus, compressive strength, tensile strength, cohesion, internal friction angle, deformation and strength failure features of model similitude material with that of prototype, the similitude materials for salt rock oil-gas storage medium are attained, which supplies reliable similitude model material for oil-gas storage geomechanical model test. |
