Impact of vibration on the transformation of oils and their viscoelastic properties
Institute of Geology and Geophysics of Azerbaijan National Academy of Sciences, AZ1143, Baku, H.Javid av., 119
Summary
A-
A+
In article are shown the laboratory experiments of low-frequency elastic oscillation impact in the range from 6-20 Hz to viscoelastic characteristic of oil from fields Pirallahi and Bibieybat.
For each frequency determined time spectrum of relaxation and rheological parameters (modulus of elasticity, true viscosity) of researched liquids. Was received, that vibration frequency increase cause of true viscosity lowering and elastic characteristics change of oil: relaxation time decrease and modulus of elasticity growth. Also specified, that to oil viscous and elastic characteristics change at vibration impact theirs physico¬chemical properties.
