摘要： The present invention provides a compact magnetic sensor capable of use in pad mounted applications and field focusing applications. The present invention provides an induction tool with a compact induction sensor having electromagnetic transmitters wound on a longitudinal core member of a C-clamp shaped transmitter core. The tool is suitable for transmitting magnetic excitation fields in multiple directions, both parallel and transverse to the tool's longitudinal axis with minimal susceptibility to errors associated with parasitic eddy currents induced in the metal components surrounding the transmitter and receiver coils. The horizontal (transverse) members of the C-clamp shaped transmitter core can be rotated to orient a magnetic excitation flux path passing between the horizontal (transverse) members and through the formation. The horizontal members can be replicated on a single longitudinal member to shape the flux path.

摘要： An apparatus and method for detecting the location of subsurface markers in a formation proximate to a borehole. The apparatus includes marker detectors in a housing having at least two housing sections attached in an initial orientation. The distance between the detectors is measured under controlled conditions with a calibration bar. The initial attached orientation between the housing sections is identified with a calibrator, and deviations from the initial attached orientation are identified by the calibrator after the housing sections are detached and reattached. The calibrator permits well site corrections to be made to the housing sections without recalibration. Gauges permit corrections for temperature and pressure fluctuations, and the corrected distances between the housing detectors is computed. Detectors in the housing generate signals when each detector is proximate to a marker in the formation, and such signals can be processed to identify the elevation of a marker in the borehole, or the distance between markers in the borehole, to determine formation compaction or settlement. In an apparatus having two detectors separated by a spacer, flexible retainers can be positioned between each detector and the spacer to permit thermal expansion or contraction of the detectors relative to the spacer.

摘要： This disclosure is directed to a detector system for use in measuring while drilling (MWD) equipment. It comprises preferably duplicate chambers positioned to one another and mounted in a MWD system where they are subject to the same shock and vibration. The shock and vibration impinge on the two chambers, and cause two output signals to be formed. The two output signals are applied to a differential amplifier so that the microphonic portion of the signal is cancelled. This then leads to a differential output signal which carries in it the signals representing nuclear events detected by the similar or duplicate detector means. Alternately, a single chamber can be used if it is provided with two anode wires and they are connected to the differential amplifier for signal cancellation.

摘要： An optical rotary joint for use in a well logging cable is set forth in the preferred and illustrated embodiment capable of transferring two or more data streams traveling along two or more optical fiber channels. The rotary joint is constructed with a stationary portion and a coacting rotary portion. A first channel of data is delivered to an optical fiber transmitted coaxially of the stationary and rotary sides of the apparatus, transfer across the rotational plane between the two components being accomplished by opposing centrally located, concentrically arranged, coacting optical lenses. A second data channel transmitted through a second optical fiber is delivered to a lens system which converts the light into a cylinder of light coaxial with the first channel and which surrounds the optical management for the first channel. All channels other than the first channel thus are converted into coaxial hollow cylinders of light. These cylinders of light are transmitted between facing lens systems in the rotary and stationary sides of the apparatus.
