Annotation:
The complex modulus of elasticity of pbmv grade bentonite drilling mud on a rotational rheometer is experimentally investigated. The dependences of the complex shear modulus on time, strain amplitude, and temperature are obtained. The obtained results provide a basis for determining the characteristics of the slow kinetics of viscoelastic modules of the investigated medium and determine the process of slow relaxation of the complex nonlinearity parameter corresponding to the equation of state of the viscoelastic medium.
Keywords:
