摘要： A fluid is received into a sample tube. A processor causes an energy to be applied to the sample tube to induce vibration in the sample tube at a resonant frequency of the sample tube containing the fluid. The processor stops the supply of energy to the sample tube. The processor monitors an amplitude of the vibration of the sample tube as the amplitude of the vibrations diminish over a period of time. The processor uses the monitored amplitude to calculate an RF of the sample tube containing the fluid. The processor uses the calculated RF to calculate the viscosity of the fluid.

摘要： A signaling apparatus comprises a magnet and a shield moveable relative to the magnet. The shield is moveable relative to the magnet between a first position in which the magnet is relatively exposed and a second position in which the magnet is relatively shielded. The apparatus can include a synchronization signal source, a downhole sensor signal source, and/or means for modulating the magnetic field in response to the signal from any source. A method of using the signaling apparatus to locate a bottomhole assembly includes moving the shield so as to modulate the magnetic field created by the magnet, sensing the modulation of the magnetic field, and determining the location of the bottomhole assembly using the information collected. The BHA can be located using phase shift or amplitude measurements. Receivers detecting the modulated magnetic field can be at or below the earth's surface.

摘要： An instrument for determining fluid properties is provided. The instrument (300) includes a tube (304) receiving the fluid, a single magnet (302) attached to the tube, and a single coil (306) wound around the single magnet. The single coil is coupled to a pulse current source (312) and receives a pulse current that creates a magnetic field in the single coil, the created magnetic field interacting with the single magnet to drive the tube to vibrate. The instrument further includes a detector (306) coupled to the tube, wherein the detector is coupled to measurement circuitry (310) and detects properties of the tube as it vibrates, and the measurement circuitry determines the fluid properties based on the detected properties. The instrument also includes a housing (314) enclosing the tube, the single magnet, and the single coil wound around the single magnet.

摘要： Disclosed is a downhole fluid resistivity sensor that includes a ceramic cylinder having a fluid-contacting surface, and at least four metal pins that penetrate a wall of the ceramic cylinder at axially-spaced locations. The pins are bonded to the ceramic to form a pressure seal. The sensor may include a circuit that injects current into a fluid via an outer two of the pins, and measures a resulting voltage via an inner two of the pins. The circuit may also provide an indication of fluid resistivity based at least in part on the resulting voltage. At each of the axially-spaced locations, a set of multiple pins may penetrate the wall to contact the fluid at circumferentially-spaced positions. The fluid-contacting surface may be an inner surface or an outer surface of the ceramic cylinder. A downhole fluid resistivity measurement method is also described.
