摘要： Oil-based mud imaging systems and methods using phase information. In some embodiments, disclosed logging systems include a logging tool in communication with surface computing facilities. The logging tool is provided with a sensor array having at least two voltage electrodes (504) positioned between at least two current electrodes (506, 508) that create an electric field in a borehole wall, and is further provided with electronics coupled to the current electrodes to determine a differential voltage between the voltage electrodes and two current flows from separate ones of the current electrodes. The differential voltage and current flows are measured as phasors defined by their magnitude and phase. The computing facilities determine borehole wall resistivity from the differential voltage and multiple current flows that include phase and magnitude information, and may display the resistivity as a borehole wall image.

摘要： Disclosed logging systems include a logging tool (34) in communication with surface computing facilities. The logging tool is provided with a sensor array having at least two voltage electrodes (504) positioned between two current electrodes (506, 508). The two current electrodes (506, 508) are each shielded with conductive shields (510, 512) to prevent current leakage into the logging tool body. A common mode voltage is measured, and the phase and amplitude of the exciting source is controlled to reduce the difference between the common mode voltage and reference voltage of a voltage detector. The logging tool (34) is further provided with electronics coupled to the voltage detector and the current electrodes (506, 508) to determine a differential voltage between the voltage electrodes (504) and current flows from the current electrodes (506, 508). From the differential voltage and multiple current flows, the computing facilities determine, and may display, the resistivity as a borehole wall image.

摘要： An apparatus and method for guarding the current injection sources of downhole logging tools utilized to determine the resistivity of an adjacent portion of a borehole wall. Two current electrodes are energized to create an oscillatory electric field in a borehole wall. The two current electrodes are each shielded with a conductive shield, maintained at the same electric potential as the current electrode, to prevent current leakage into the logging tool body. A current sensor is coupled between each current electrode and conductive shield to measure the actual current flow injected into the borehole wall from the current electrode and to compensate for current leakage. A voltage detector measures the differential voltage created by the electric field in the borehole wall, and the differential voltage is used in combination with the measured current flow to determine a resistivity value for the borehole wall.
