摘要： Borehole data presentation systems and methods that facilitate communication of volumetric logging data to a surface processing system for presentation to a driller or other user interested in visualizing the formations surrounding a borehole. The disclosed systems optionally tailor the telemetry stream to match the chosen display technique, thereby maximizing the logging system utility for the driller. Variable opacity of certain data regions or certain data discontinuities greatly facilitates data comprehension, particularly when true three-dimensional display technologies are employed. Holographic or stereoscopic display technologies may be employed to show the three-dimensional dependence of measured formation properties such as resistivity, density, and porosity. Alternatively, the radial axis can be used to represent a formation parameter value, thereby enabling cylindrical cross-plots of multiple measurements. The user can control viewing position and orientation to more fully explore the three dimensional representation.

摘要： A method and apparatus for surveying a borehole using a rotating sensor package. A sensor tool preferably including a magnetometer sensor array is disposed in the bottom hole assembly of a drillstring. Conditioning circuitry in the sensor tool processes the sensor readings from the sensor array taken while the drillstring is rotating. In one embodiment, the conditioning circuitry includes processing circuitry adapted to adjust the sensor readings to account for an analytically predicted level of axial current induced in the drillstring as a result of its rotation in the Earth's magnetic field. In another embodiment, a current generator is provided to generate a counter-current intended to cancel the analytically predicted level of axial current induced in the drillstring as a result of rotation in the Earth's magnetic field. In another embodiment, insulating members are disposed above and/or below the sensor tool to prevent conduction of rotation-induced current therein. In still another embodiment, the sensor tool is disposed in a drill collar that is composed of a non-conducting material, such that no rotation-induced current is conducted through the sensor tool.

摘要： Downhole positioning systems and associated methods are disclosed. In some embodiments, the system comprises a downhole source, an array of receivers, and a data hub. The downhole source transmits an electromagnetic positioning signal that is received by the array of receivers. The data hub collects amplitude and/or phase measurements of the electromagnetic positioning signal from receivers in the array and combines these measurements to determine the position of the downhole source. The position may be tracked over time to determine the source's path. The position calculation may take various forms, including determination of a source-to-receiver distance for multiple receivers in the array, coupled with geometric analysis of the distances to determine source position. The electromagnetic positioning signal may be in the sub-hertz frequency range.

摘要： A method and system for designing bottom hole assembly configuration. The system and method include modeling the bottom hole assembly by dividing complicated BHA configurations into independent modules and segments. Modules are bounded by two stabilizers where segments are bounded by bottom hole assembly components. A recursive process is used to derive solutions for each of the segments and modules. Only two unknowns (and two non-linear equations) are left when the recursive process reaches to the bit. The two unknowns are then solved by iteration.

摘要： An electromagnetic borehole telemetry system providing improved signal to noise ratio. Adaptive filters use noise channels as references to remove noise from the signal channel. Directional detectors provide a signal channel with reduced noise content and improved noise channels with reduced signal content. Directional detectors may be magnetometers aligned with the magnetic field, or antennas aligned with the electric field, of signal or noise sources. Alignment may be performed by beam steering of the outputs of a three-channel detector, which may detect both signal and noise.

摘要： An NMR measurement-while-drilling tool having the mechanical strength and measurement sensitivity to perform NMR measurements of an earth formation while drilling a borehole, and a method and apparatus for monitoring the motion of the measuring tool in order to take this motion into account when processing NMR signals from the borehole. The tool has a permanent magnet with a magnetic field direction substantially perpendicular to the axis of the borehole, a steel collar of a non-magnetic material surrounding the magnet, antenna positioned outside the collar, and a soft magnetic material positioned in a predetermined relationship with the collar and the magnet that helps to shape the magnetic field of the tool. Due to the non-magnetic collar, the tool can withstand the extreme conditions in the borehole environment while the borehole is being drilled. Motion management apparatus and method are employed to identify time periods when the NMR measurements can be taken without the accuracy of the measurement being affected by the motion of the tool or its spatial orientation.

摘要： An apparatus and method for determining formation resistivity at a plurality of radial distances from an earth borehole uses a single receiver pair and a plurality of electromagnetic energy transmitters sequentially spaced along the apparatus from the receiver pair, such transmitters being sequentially pulsed at approximately 1-2 MHz each to provide time separation between the pulsing of the plurality of transmitters. The closest spaced transmitter is spaced a predetermined distance from the closer receiver to make the depth of investigation of the closest transmitter essentially independent of formation resistivity. Alternatively, a single transmitter is spaced a predetermined distance from the closer receiver to make the depth of investigation of such transmitter essentially independent of formation resistivity.

摘要： The present invention is directed to a system, apparatus and methods for determining influx of formation fluids into a well borehole during drilling. The methods of the present invention comprise determining the dielectric constant and/or conductivity of the fluid in the annulus about a drill pipe in a well borehole, comparing the determined dielectric constant and/or conductivity to a reference value and inferring that influx has occurred when the difference between the dielectric constant and/or conductivity and the reference value is greater than a predetermined limit. The dielectric constant and/or conductivity is determined by transmitting electromagnetic energy between about 10 KHz and about 10 GHz through the fluid in the annulus about the drill pipe from a transmitter located in the drill pipe section, receiving a portion of that energy which has travelled through the fluid but not through the surrounding formation in a receiver located in the drill pipe, and determining the dielectric constant and/or conductivity as a function of at least one of the phase and the amplitude of the received energy.
