Abstract
An apparatus for determining an initiation point of cement curing, with a vessel for containing at least a portion of freshly mixed cement, means for passing an electric signal through the cement, means for detecting an abrupt change in a dielectric or electric property of the cement as a result of the electric signal and a display unit for displaying the initiation point of polymerization of the cement from the abrupt change in the dielectric or electric property detected, the change in the dielectric or electric property being a phase shift in the electric signal passed through the cement or a change in capacitive properties of the cement or a change in resistivity of the cement.
Claims18
An apparatus for determining an initiation point of cement curing, comprising a vessel for containing at least a portion of freshly mixed cement, means for passing an electric signal through the cement, means for detecting an abrupt change in a dielectric or electric property of the cement as a result of the electric signal and a display unit for displaying the initiation point of polymerization of the cement from the abrupt change in the dielectric or electric property detected, the change in the dielectric or electric property being a phase shift in the electric signal passed through the cement or a change in capacitive properties of the cement or a change in resistivity of the cement.
An apparatus for determining an initiation point of cement curing, comprising a vessel for receiving the cement, electrodes connected to the vessel and configured to pass an electric signal through the cement, and at least one sensor configured to monitor a dielectric or electric property of the cement as a result of the electric signal and detect an abrupt change therein, and a monitoring system connected to the at least one sensor and configured to display the initiation point of polymerization of the cement from the abrupt change in the dielectric or electric property detected, the change in the dielectric or electric property being a phase shift in the electric signal passed through the cement or a change in capacitive properties of the cement or a change in resistivity of the cement.
