摘要： A downhole fluid analysis system includes an optical sensor comprising, which includes a light source configured to emit light comprising a plurality of wavelengths, a light detector, and an optical tip through which at least a portion of the light travels and returns to the detector, wherein the incident angle of the light causes total internal reflection within the optical tip. The system further includes a piezoelectric helm resonator that generates a resonance response in response to an applied current, and an electromagnetic spectroscopy sensor positioned symmetrically with respect to the piezoelectric helm resonator in at least one direction. The light may be reflected in the optical tip at one or more reflection points, and each reflection point may generate an evanescent wave in a medium surrounding the optical tip. The light may be internally reflected in the optical tip at a plurality of reflection points.

摘要： A downhole fluid analysis device includes a piezoelectric helm resonator, an optical sensor, and an electromagnetic spectroscopy sensor. The piezoelectric helm resonator includes a strain bar and a pair of electrodes coupled to opposite sides of the strain bar. The piezoelectric helm resonator further includes a pair of tines, in which a first tine of the pair of tines is coupled to opposite ends of the strain bar, the pair of tines each having an arc, and such that strain across a transverse face of the strain bar generates a resonance response from the pair of tines. The optical sensor is positioned centrally with respect to the piezoelectric helm resonator, and the spectroscopy sensor is positioned symmetrically with respect to the piezoelectric helm resonator in at least on direction.

摘要： Embodiments of the present disclosure include a method for determining at least one fluid property that includes obtaining electrical admittance data from a downhole tool, the admittance data being associated with a fluid in a wellbore. The method also includes obtaining reference electrical admittance data for air. The method further includes comparing the admittance data to the reference admittance data. The method also includes determining an offset between a first peak of the admittance data and a second peak of the reference admittance data. The method includes determining the at least one fluid property based at least in part on the determined resonance frequency offset.

摘要： A computer-implemented method includes receiving a plurality of sensor signals, each signal of the plurality of sensor signals being tagged with an associated time and depth. The method also includes selecting a baseline signal. The method further includes comparing a selected sensor signal, of the plurality of sensor signals, to the baseline signal. The method also includes determining a difference between the baseline signal and the selected sensor signal exceeds a threshold. The method includes identifying, based at least in part on the difference, a feature of interest associated with the selected sensor signal.

摘要： An asset identification system includes a tool having an axial dimension and a radial dimension. There are three RFID devices located on the tool, and the three RFID devices are located at equal angles with respect to each other in the radial dimension. The system further includes a storage apparatus configured to store the tool, and an RFID reader. At least one of the three RFID devices located on the tool is readable by the RFID reader regardless of the radial orientation of the tool with respect to the RFID reader.

摘要： A method for determining a wellbore fluid phase includes receiving, from a first sensor, first fluid data for a fluid flowing through a wellbore. The method also includes receiving, from a second sensor, second fluid data for the fluid.

The method also includes determining, based at least in part on the second fluid data, a second fluid property. The method further includes determining a relationship between the first fluid property and the second fluid property, the relationship based at least in part on respective evaluations of the first fluid property with respect to a first threshold and the second fluid property with respect to a second threshold. The method includes determining, based at least in part on the relationship, a phase of the fluid.
