摘要： A correction method for resistivity measurements of formation surrounding a borehole includes deploying a logging tool in the borehole and having a standoff in between the logging tool and the wall of the borehole, measuring a total current entering into the pair of current electrodes, computing a leakage current in the sensor pad caused by an internal capacitive impedance between the pair of current electrodes and the main body of the sensor pad, computing a measuring current to enter into the formation for the resistivity measurements by subtracting the leakage current from the total current, computing an external capacitive impedance between the current electrodes and the formation, utilizing a pre-built chart to obtain a geometric factor based on the external capacitive impedance, and computing resistivity of the formation based on the geometric factor.

摘要： An apparatus for making resistivity measurements near a drill bit includes a tool body, a transmitter deployed on the tool body, a receiver deployed on the tool body and at an axial distance from the transmitter, and a transmitting signal coupler coupled to the transmitter antenna and the receiver. The transmitter generates electrical signals and converts the electrical signals into electromagnetic signals to be transmitted. The receiver measures the amplitudes and phases of the electromagnetic signals received from the transmitter. The transmitting signal coupler couples a portion of the electrical signals from the transmitter antenna and measures the amplitudes and phases of the coupled electrical signals. Amplitude attenuation and phase shift between the electromagnetic signals received at the receiver and the electrical signals coupled at the transmitting signal coupler are computed for calculating resistivity.
