摘要： A steerable, magnetic dipole antenna for Measurement-While-Drilling (MWD) or Logging-While-Drilling (LWD) applications. The antenna elements use a hole arrangement in addition to grooves in a steel tool body, which is typically a drill collar. This antenna embodiment is extremely robust, meaning that does not significantly reduce the structural integrity of the tool body in which it is disposed. The antenna embodiment is also relatively wear resistant. The resultant magnetic dipole generated by this antenna is also electrically steerable in inclination angle from a common origin. A variable dipole moment inclination angle combined with independently measured tool rotation orientation during normal drilling allows the antenna to generate a magnetic dipole moment that may be directed at any three dimensional angle and from a common origin point at the centroid of the antenna. The antenna can also be embodied to be more sensitive to resitivity in a particular azimuthal direction.

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： An NMR apparatus includes permanent magnets oppositely polarized in the axial direction and suitably arranged along the axis of the apparatus to produce a nearly radial static magnetic field in a toroidal examination region within the rock formation surrounding the wellbore. A first coil is wound around a cylindrical annulus core coaxial with the magnets, the core including high magnetic permeability material. The first coil produces pulsed RF magnetic fields oriented parallel to the axis of the apparatus and thus perpendicular to the static magnetic field in the toroidal examination region. This reorients certain nuclear spins and the bulk magnetization of the formation within the examination region resulting from them. The first coil picks up on component of the spin-echo signals of the precessing nucleii. A second coil toroidally wound around the same cylindrical annulus core in the form of a torus with windings in planes parallel to the axis of the apparatus detects a second component of the spin-echo signals. The apparatus also includes a third coil spaced apart from the first coil and having a geometry similar to that of the second coil. An electrically conducting collar shields the third coil from the magnetic fields produced elsewhere in the apparatus. A processor combines the signals from the three coils to give spin-echo signals with improved signal-to-noise ratio.

摘要： The present invention is directed to a measurement-while-drilling logging tool which includes a minimum number of analog electrical and electronic components, and which instead utilizes digitally-controlled electronic and electrical components to obtain an accuracy which is not possible utilizing prior art measurement-while-drilling logging tools. Additionally, the present invention allows for calibration operations to be conducted before, during, and after logging operations. Preferably, the calibration operations are performed periodically or intermittently during logging operations, and recorded, to be utilized later in explaining any irregularities in the log data. This calibration operation during drilling operations is not found in prior art devices, and is rendered practical by the utilization of digitally-controlled electrical and electronic components in lieu of analog components which are traditionally utilized in logging tools. The logging tool of the present invention also allows for the periodic calculation of the undesirable magnetic field mutual coupling between particular receiving antennas. Once the value of the magnetic mutual coupling is calculated, it may be recorded for future use, or automatically subtracted from particular measurements, greatly enhancing the accuracy of logging operations. Finally, the measurement-while-drilling logging tool of the present invention can perform for the first time accurate borehole calipering operations, due in large part to the great accuracy associated with the particular components selected of the preferred embodiment of the present invention.

摘要： A method and apparatus is disclosed for performing measurement-while-drilling operations in a borehole to interrogate the borehole and the surrounding formation utilizing electromagnetic fields. A measurement sonde is provided which includes at least one of (a) a transmitting member for generating an interrogating electromagnetic field for passage through the borehole and surrounding formation, and (b) a receiving member for receiving an interrogating electromagnetic field after passage through said borehole and surrounding formation. A measurement tubular is provided, which includes a central bore which communicates with the central bore of the drillstring. The measurement tubular couples in the drillstring in a selected location, and permits interrogation of the borehole and surrounding formation with the interrogating electromagnetic fields generated by the measurement sonde. Preferably, the measurement tubular is formed at least partially of a non-conducting or poorly-conducting material which will allow the inward and outward passage of electromagnetic fields. The measurement sonde is secured within the central bore of the measurement tubular. Preferably, it is releasably secured therein, and can be run in and out of the wellbore during drilling operations without substantial interference with drilling operations.

摘要： An electromagnetic antenna for Measurement-While-Drilling (MWD) applications is disclosed. The antenna can include several array elements that can act alone or together in various measurement modes. The antenna elements can be disposed in tool body recesses to be protected from damage. The antenna elements can include a ferrite plate crossed or looped by independent current carrying conductors in two or more directions forming a bi-directional or crossed magnetic dipole. Although disclosed as a MWD system conveyed by a drill string, basic concepts of the system are applicable to other types of borehole conveyance.
