METHOD FOR THE ISOBARIC TRANSFER OF A FLUID FROM A DEPOSIT AND DEVICE FOR IMPLEMENTING SUCH A METHOD

摘要

The invention relates to method for transferring under pressure a fluid extracted from the deposit by means of a sampling vessel (5) wherein the fluid sample is maintained at the reservoir pressure or extraction pressure, as well as to the method for determining at least one thermodynamic characteristic of this fluid, particularly a method for determining phase transition envelops. The invention also refers to a method combining the implementation of the scanning transitiometry with spectroscopic or analytical techniques, eventually in the presence of a fluid in a supercritical state. The invention similarly refers to a device for implementation of the above-referred methods.
