    摘要： Devices, methods and systems for making optical measurements of a fluid at elevated pressures and temperatures are disclosed. A cell is designed for the optical spectroscopic measurements of fluids or gas using light from ultra violet (UV) to far infrared wavelengths, among other wavelengths. A cell is described that is well suited for applications using very small fluid volumes, on the order of micro liters, such as microfluidic systems. Some described embodiments are suited for very high pressure and temperature environments (for example, 20 kpsi or greater at 175 degree C. or greater). Such conditions, for example, may be found in oilfield downhole environments. Some embodiments provide are inexpensive, and make use of replaceable lenses that are used as a pressure barrier and for collimation of the optical beam path for spectroscopic measurements.

    摘要： A method and an apparatus for nucleating bubbles in an oil-gas mixture, including introducing a sample comprising an oil-gas mixture into a chamber; and heating the sample with a heater until at least one bubble is thermally nucleated in the chamber. The bubble point (BP) pressure of the sample can be determined by detecting pressure at two points in a system, which includes the chamber and the heater, and by determining the behavior of the nucleated bubble as the pressure on the bubble is varied.

    摘要： The present invention recited a method and apparatus for measuring a parameter of a fluid within a fluid channel using a tracer element injection by an injection element and detected by a detection element at a location separate from the injection element location. The injection element and detection element of the present invention are in communication with a computational element, wherein the computation element is capable of measuring a parameter of a fluid in a fluid channel based upon time of flight data derived from the injection element and the detection element.
