SAMPLING METHOD OF FLUID SAMPLES FROM PIPELINE, AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2012 - IPC G01N1/10 

FIELD: oil and gas industry.

SUBSTANCE: sampling method of fluid samples from pipeline involves the following operations: fluid flow rate is pre-determined in pipeline on the following basis: when sample is being taken by means of one sampling element, the latter is chosen with its inlet surface area determined depending on the specified sampling speed at the inlet of sampling element and the required sample flow rate for quality analysers, on condition of pipeline fluid flow rate change at pre-determined interval, inlet of sampling element is installed so that its inlet faces the flow; fluid is pumped via pipeline, and some fluid is pumped and sample is taken through sampling element and additional pipeline connected to it. Pipeline fluid sampling device includes sampling element, erection assembly, sampling assembly and additional pipeline for sample transportation with continuous quality analyser installed on it.

EFFECT: manufacturability and efficiency of sampling, reliability and convenience during implementation of the method and operation of the device.
