摘要： A well logging tool adapted for use in a borehole traversing an earth formation includes at least one sensor sensing at least one characteristic of the earth formation. Another sensor senses the ambient temperature and provides a corresponding temperature signal. An output circuit provides a temperature compensated output signal corresponding to the sensed characteristic of the earth formation in accordance with the temperature signal and the characteristic signal.

摘要： A dielectric well logging system is provided to determine dielectric constant and resistivity in formations invaded by water to determine oil and water saturations of the formations. Plural transmitters are activated in a time division multiplex manner and sensed by receiver coils. The amplitude ratio and phase difference between the signals sensed by the receiver coils are then used to determine dielectric constant and resistivity which may then be used to determine invasion characteristics.

摘要： Electrical energy is induced into an earth formation by a transmitter in apparatus, adapted to be passed through a borehole traversing the earth formation. Clock pulses are also provided in the apparatus. At least two receivers provide signals corresponding to received electrical energy from the earth formation. A gating circuit provides groups of clock pulses in accordance with the signals from the receivers so that the number of clock pulses in each group corresponds to the dielectric constant of the earth formation.
