摘要： A technique facilitates the monitoring of thermodynamic properties of reservoir fluids. The technique utilizes a modular sensor assembly designed to evaluate a sample of a hydrocarbon-containing fluid within a cell body. A variety of sensors may be selectively placed into communication with a sample chamber within the cell body to evaluate the sample at potentially high pressures and temperatures. The sensors may comprise a density-viscosity sensor located in-situ to efficiently measure both the density and viscosity of the sample as a function of pressure and temperature. Other sensors, such as an optic sensor, may also be positioned to measure parameters of the sample while the sample is retained in the sample chamber.

摘要： The apparatus of the present invention include an optical fiber with a Bragg grating formed along a portion of its core and a mechanical structure arranged adjacent to the Bragg grating for amplifying transverse strain on the fiber in the vicinity of the grating. In particular, the mechanical structure is designed to convert ambient pressure into transverse strain on the fiber in the vicinity of the grating. The methods of the invention include converting pressure into transverse strain on an optical fiber, amplifying the effect of pressure on the transverse strain, measuring pressure by determining the spacing between spectral locations related to peaks (or minimums) of light reflected from an optical grating subjected to transverse strain, and measuring the temperature of the grating by determining the locations of the spectral locations related to the peaks (or minimums) of light reflected from the grating. According to one embodiment, the mechanical structure includes a piston mounted in a transducer body through which the optical fiber passes.
