SAMPLER Russian patent published in 2024 - IPC E21B49/08 G01N1/10 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil and gas industry, namely to extraction, collection, preparation and transportation of liquid and gas products, and can be used for fluid sampling from pipelines. Disclosed is a sampler, which includes a pipeline, a housing connected to the pipeline by inlet and outlet taps, valve communicated by one end with the inner cavity of the pipeline, and with the other one – with the sampling container, a liquid flow swirler installed inside the pipeline before the inlet branch, and a device concentrically installed in the pipeline after the swirler, which narrows the liquid flow. Sampler housing is located on top of the pipeline. Swirler is made in the form of a thread, a spiral or a spring with a constant pitch on the inner surface of the pipeline. At the outlet of the device, which narrows the liquid flow, is equipped with a branch pipe with internal diameter, which provides for turbulent liquid flow, and the valve is interconnected inside the pipeline with the branch pipe of the above device. Inlet branch is equipped with a coaxial tube with an L-shaped outlet located coaxially to the pipeline, directed against the liquid flow and communicated with the swirler for removal of the gas released in the swirler from the liquid into the housing.

EFFECT: reduction of measurement error due to sampling along the whole diameter of the pipeline with preliminary gas separation.
