Assessment of Rheological Properties of Bazhenov Formation by Thermobaric Test Data

The performed thermobaric tests of cylindrical bazhenite specimens consisted in recording of time variation in height of the specimens, h ( t ), under constant axial loading at varied temperature T . The authors demonstrate that under rapid increase/decrease in T deformation process obeys the thermo...

Summary:The performed thermobaric tests of cylindrical bazhenite specimens consisted in recording of time variation in height of the specimens, h ( t ), under constant axial loading at varied temperature T . The authors demonstrate that under rapid increase/decrease in T deformation process obeys the thermoelastic law and calculate the coefficient of linear temperature expansion. Under constant increased temperature, the process of deformation is described using the viscoelastic Voigt model. The authors formulate and solve inverse problems on elastic moduli and viscosity of rocks by the data of h ( t ).
