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.

Key words: salt rock, oil and gas storage medium, similitude condition, similitude material, geomechanical model test
