    摘要: A method and apparatus are provided for insulating electrical connections to a resonator from fluid downhole under extreme pressure and temperature conditions downhole. The method and apparatus provide a pliable insulator that maintains electrical isolation between a resonator electrical connection during exposure to high pressures downhole. The insulator is substantially chemically non reactive so that the insulator maintains electrical isolation between the resonator electrical connections during exposure to fluids downhole. The insulator has a thermal coefficient of expansion in a range so that the insulator maintains electrical isolation between the resonator electrical connections during exposure to high temperatures downhole.

    摘要: The present invention provides an apparatus and method for randomly distributing a number of fibers associated with a spectral channel over an area of an input optics head input window for sensing optical input. The head comprises a plurality of optical channels each channels having a plurality of fibers spread out and intermingled across the input optics head. Thus, a particle or gas bubble passing in front of the input optics head would temporarily affect all channels but only to a small degree since only a portion of fibers for a particular channel would be affected by the temporary passage of the bubble or particle passing in front of a particular region of the optics head input window.

    摘要: A cooling system in which an electronic device or other component is cooled by using one or more solid sources of liquid vapor (such as polymeric absorbents, hydrates or desiccants that desorb water at comparatively low temperature) in conjunction with one or more high-temperature vapor sorbents or desiccants that effectively transfer heat from the component to the fluid in the wellbore. Depending on the wellbore temperature, desiccants are provided that release water at various high regeneration temperatures such as molecular sieve (220–250° C.), potassium carbonate (300° C.), magnesium oxide (800° C.) and calcium oxide (1000° C.). A solid water source is provided using a water-absorbent polymer, such as sodium polyacrylate. Heat transfer is controlled in part by a check valve selected to release water vapor at a selected vapor pressure.

    摘要: A method of analyzing acoustic data comprising, determining fluid sound speed through connate fluid. The method involves sampling the fluid, sending an acoustic signal into the fluid between a first and a second reflective interface. Data is recorded that represents acoustic signals over time as they are reflecting from the interfaces. A smoothed first derivative with respect to time of the cumulative sum of squares (CSS) of the filtered amplitude data is determined. This first derivative is cross correlated to the time-shifted versions of itself.

    摘要: The present invention provides a method and apparatus for estimating a property of a fluid downhole by exposing the fluid to modulated light downhole and sensing changes in intensity of infrared radiation from the downhole fluid to estimate the property of the downhole fluid. The present invention senses changes in intensity of light by converting the changes to transient changes in temperature of a detector, such as a pyroelectric detector. The present invention performs spectroscopic analysis of fluids by optically filtering the light allowed to impinge on a pyroelectric detector, converting the changes in temperature of the pyroelectric detector to a signal and converting the signal to estimate the property of the downhole fluid. The light source is modulated by mechanically chopping the beam or by electrically pulsing the light source or by steering the beam between different path lengths of sample or between a reference cell (filled with a reference fluid or empty) and a sample-filled cell.
