A nuclear flowmeter for measurements in multiphase flows consisting of up to three main phases that is connected in series in the output flow in a production line of an oil well, that includes a “U” shaped arrangement formed by an input branch and an output branch placed at both sides of the “U” shaped arrangement, where the input branch is connected to the production line of the oil well through an input pipe section (1) and the output branch is connected to the line of production of the oil well through an output pipe section (21) placed respectively at both ends of the “U” shaped arrangement; the input branch includes a pipe section with section reduction that forms a Venturi (3) while in the output branch includes a pipe section with possible section reduction (5) where the nuclear measurements are made, is provided.
A nuclear flowmeter for measurements in multiphase flows comprising up to three main phases that are connected in series to a production line of an oil well, where the pipe section of the output branch is placed between a storage, shield and transport compartment of an isotopic “fast” neutron source that includes said isotopic “fast” neutron source and neutron detectors included in the respective supports.
A nuclear flowmeter for measurements in multiphase flows comprising up to three main phases that are connected in series to a production line of an oil well, having a discrimination principle between the constituent phases (water, oil and/or gas) which falls over the moderation of the neutrons that is produced within the conduct,
The nuclear flowmeter for measurements in multiphase flows comprising up to three main phases that are connected in series to a production line of an oil well, where an exclusive cavity is incorporated to store a sample of a liquid phase extracted from an adjacent fluid through (30, 22, 23) and where within said dedicated cavity a gaseous phase has been separated and a liquid is injected, consisting of water/oil included in said dedicated cavity, to be radiated by the same isotopic “fast” neutron source, for a subsequent detection of gamma photons produced by the decay of isotope N-16 as a result of the reaction O-16(n,p)N-16*;
