Abstract.
The work presents an original method for physical modeling of gas-and-water saturation of rocks and, in particularly, in sandstones which differ by binder components and porosity. The rocks are saturated with gas and water simultaneously with effect of vacuum formation by the Mendeleev-Clapeyron law in the rock structure during the rock cooling in hot water with simultaneous impact of the vacuum on the heated water with the sample. It is stated that at gas-and-water saturation sandstone with quartz cement and porosity of 1% is harden, but if the structure is at least slightly disturbed such strength characteristics as tensile strength and elastic modulus as well as specific energy accumulated by the sample under uniaxial compression before its destruction can decrease by 37, 38 and 43%, respectively.
Keywords:
gas-and-water saturation, modulus of elasticity, tensile strength
