FIELD: oil-and-gas industry.
SUBSTANCE: invention relates to oil-and-gas industry and can be used in analysing fluid dynamics of gas medium at hydrocarbons deposits and subterranean gas storages. The proposed method comprises forcing gas medium indicator marks representing gas-filled micro granules with the dispersion degree of 0.5 to 0.6 µ into the bench through different injection holes and sampling from output holes. Note that indicator mark sampling is realised by forcing gas through sampling tube along with controlling gas passing time and the hole rate of yield, the sampling tube gas flow rate is determined from mathematical expression. The content of micro particles in indicator mark is determined from mathematical expression. The invention covers also the device to embody the above-described method.
EFFECT: continuous sampling, higher sampling efficiency and validity of results.
