    摘要： Example methods, apparatus and articles of manufacture to process measurements of wires vibrating in fluids are disclosed. A disclosed example apparatus includes a downhole assembly and a surface assembly. The downhole assembly including a sensor to measure a waveform representative of a motion of a wire vibrating within a fluid at a downhole location in a wellbore, a waveform modeler to compute a model parameter from the measured waveform, and a first telemetry module to transmit the computed model parameter to a surface location. The surface assembly including a second telemetry module to receive the computed model parameter from the downhole assembly, and a viscosity analyzer to estimate a viscosity of the fluid from the computed model parameter.

    摘要： Vibrating wire viscometers are disclosed. An example apparatus to determine the viscosity of a downhole fluid is described, the apparatus including a wire to be immersed in a downhole fluid, to vibrate when an alternating current is applied to the wire within a magnetic field, and to generate an electromotive force when vibrating within the magnetic field, the wire comprising a first resistance. The apparatus further includes a nulling circuit coupled to the wire, wherein the nulling circuit comprises a second resistance that is selectable to be substantially equal to the first resistance, and an analyzer coupled to the wire and the nulling circuit to determine the first resistance, the second resistance, and a viscosity of the downhole fluid based on the first and second resistances, at least one characteristic of the wire, and the electromotive force.

    摘要： A receptacle (10) for use in collecting samples down a well bore (14) is provided, the receptacle comprising a plurality of interconnecting modules (22, 24, 26, 30, 32, 34). A main chamber (22) is capable of holding a sample, and sensors (58, 60, 62, 64) within the chamber detect physical and chemical characteristics of the sample. Valves (50, 52) in a chamber wall seal the chamber (22) after a fluid sample has been collected. A communication means is placed in communication with the chamber (22) so as to provide an externally accessible port which communicates with the inside of the chamber (22) and allows detection and analysis of sample characteristics without removing the sample from the sealed chamber (22). The chamber (22) includes a piston (82) which is adjustable to keep pressure constant in the chamber and a heating element (58) to keep temperature constant. A method for sampling downhole fluids is also provided.
