【Abstract】 The relationships of the seal and compressive strength of magnetic viscoelastic body changing with the contents of magnetic powder and surfactant have been educed according to the experimental study on the compressive performance of magnetic viscoelastic body made by the prescriptions of different contents of magnetic powder and surfactant.A prescription of magnetic viscoelastic body suitable for magnetic seal has been optimized by the results.A series of experimental studies have been done to test the performance of optimized prescription of magnetic viscoelastic body.It indicated that the optimized magnetic viscoelastic body has advantages of high pressure-resistance,high temperature-resistance,good stability etc.,and it is suitable for magnetic seal in water/oil wells or other industries.更多还原
