Method and device in order to investigate the pharmacological of a multiphase fluid under pressure, such as a fluid petrolier in a conduit

摘要

To study the properties of a multiphase fluid under pressure flowing along a duct, such as the petroleum stream produced by an oil well, a fraction of the fluid is taken from a substantially vertical first length of the duct within which the fluid is agitated and flows upwards, and this fraction is transferred into a separator receptacle with the top of said receptacle being connected to a second length of the duct located downstream from the first length and at a slightly lower pressure relative thereto. Thereafter, the volume ratio of the liquid phases can be determined, e.g. by pouring them into the separator receptacle and measuring the levels thereof, or by causing the liquid emulsion to flow through an appropriate sensor device and where the emulsion density can be determined by weighing the separator receptacle before and after such a liquid phase/emulsion pouring step.
