摘要： The invention is a method for determining the Joule-Thomson coefficient of a fluid, expressing the temperature variation in relation to a pressure variation thereof. The fluid is injected at a determined injection temperature into a thin tube (8) (preferably a capillary tube in order to obtain a high pressure drop with reasonable flow rates) which contains a temperature detector (TC1) leading to a pressure drop for the fluid. The temperature variation of the fluid in relation to the injection temperature is measured by means of this temperature detector. The pressure drop undergone by the fluid in tube (8), due to the presence of this temperature detector, is also measured and the Joule-Thomson coefficient is calculated by combination of measurements of the pressure drop and of the temperature variation of the fluid. The method can be applied notably in the field of hydrocarbon production, more particularly hydrocarbons coming from high-pressure and high-temperature reservoirs and in gas lines.
