摘要： Methods and apparatus for decreasing a density of a downhole fluid are described. An example apparatus to analyze a downhole fluid includes a chamber to decrease a density of at least a portion of a sample of a downhole fluid. Additionally, the example apparatus includes a sensor to measure a pressure of at least the portion of the sample in the chamber. Further, the example apparatus includes a fluid measurement unit to measure a characteristic of at least the portion of the sample based on a relationship between the pressure of at least the portion of the sample in the chamber and a predetermined pressure. Further yet, the example apparatus includes a control unit to determine a parameter of the downhole fluid based on the characteristic.

摘要： An electrochemical sensor for measuring contents of a fluid or gas at high pressure and/or high temperature, for use, for example, in a wellbore for hydrocarbon applications, is provided. The sensor includes: a bulkhead-like electrode assembly including a cylindrical housing and a cylindrical electrode structure. The cylindrical electrode structure includes a cylindrical conductive pin extending from a high pressure region to a low pressure region and an electrode connected to one end of the pin at the high pressure region and having an electrode surface for exposure to a flow path of the fluid or gas in the high pressure region. At least a part of the surface of the pin is protected from direct contact with the fluid or the gas by an insulating coating impermeable to the fluid or gas. The pin may include an alternating pattern of protruding and receded portions.
