摘要： A logging apparatus is provided for use in a wellbore for measuring an attribute of at least one of the wellbore and a surrounding formation, when coupled to a wellbore tubular expended in the wellbore. The logging apparatus includes a housing, at least one transmitter, and at least one receiver. The transmitter is carried by the housing and is individually and selectively operable for producing electromagnetic interrogating signal at selected interrogation frequency for passage to the wellbore and surrounding formation. The receiver is carried by the housing in a selected position relative to the transmitter, and is tuned to receive electromagnetic signals at the interrogation frequency to the exclusion of other frequencies. A portion of at least one of the wellbore, and surrounding formation has an attribute value which can be derived from at least one of amplitude attenuation of electromagnetic interrogating signal as determined from measurements of the electromagnetic interrogating signals taken through the receiver, and phase shift of electromagnetic interrogating signal as determined from measurements from electromagnetic signal taken through the receiver. The apparatus further includes means for sampling signals from the receiver or receivers at a sampling frequency which is less than the interrogation frequency. A controller member is provided for selectively energizing the transmitters and for selectively obtaining measurements of the electromagnetic interrogating signal with the receivers, and determining an accurate measure of the attribute value.

摘要： The present invention is a propagation resistivity system that utilizes one or more transmitter coil antennas, or “transmitters” and at least two receiver coil antennas, or “receivers”. The system uses a wellbore resistivity tool which may be embodied as a MWD tool or as a wireline tool. Two or more transmitters may be spaced equally on either side of two or more spaced-apart receivers. Two or more frequencies are transmitted and received simultaneously. Multiple frequencies may be transmitted from each transmitter or from separate transmitters at the same time. Multiple frequencies are simultaneously received and analyzed by the receiver electronics, thereby reducing the measurement time for multiple frequency measurements. In one embodiment each of two transmitters transmits simultaneously. One transmitter operates on a high frequency. The second transmitter operates at a lower frequency. The higher frequency signal penetrates a relatively shallow radial distance into the formation and the lower frequency penetrates to a radial depth which exceeds the higher frequency. Composite measurements made at two radial depths are used to compensate for factors having adverse effects on resistivity measurements in the immediate region of the borehole. Such factors include invasion, variations in borehole size, variations in borehole fluid, and the like.

摘要： A method and system is provided for minimizing delays in a magnetic ranging method. Delays are minimized by establishing synchronicity between triggering of a three-axis magnetometer and energisation of a solenoid assembly deployed in the borehole being drilled and the first borehole, respectively. Synchronicity enables measuring various components of the alternating magnetic field created by energisation of the solenoid assembly by the magnetometer, the moment the solenoid assembly is energised. The recorded components are used for computation of steering data for drilling the second borehole relative to the first borehole. The steering data can be determined at the surface or downhole.

摘要： An electrode insulated from and mounted to the outside of a drill collar in a drill string positioned in a borehole is used for measuring formation spontaneous potential. A current measuring device, such as an ammeter, is connected through a varible ammeter resistor and a switch between the electrode and the drill collar. The ammeter measures current flow from the formation along the walls of the borehole to the drill string to determine the spontaneous potential of the formation at various points along the borehole while it is being drilled. The switch in the ammeter circuit is interrupted at a pre-selected rate and the ammeter current signal is connected through a lock-in amplifier to cancel random noise in the signal and produce an accurate measurement of the very small currents flowing between the electrode and the drill collar. The currents are indicative of spontaneous potentials in the formation. The value of the ammeter resistor is varied and the frequency of closure of the switch is swept over a pre-selected range to measure the time constant of the polarization of the formation along the borehole.

摘要： The present invention provides a measurement-while-drilling (MWD) system having a downhole computer and multiple downhole sensors. Relatively large amounts of basic or "raw" data are measured by downhole sensors, and these data are processed within a downhole computer to be reduced to parameters of interest, which may be utilized to control the drilling operation by downhole devices, stored downhole, telemetered to the surface, or both. The measurements may be correlated downhole with stored reference data thereby providing additional information pertaining to the drilling operation. Downhole depth correlation between downhole measured parameters may be made by utilizing surface determined or downhole determined borehole depth.
