FIELD: oil industry.
SUBSTANCE: group of inventions relates to technology and sampling techniques of media, subject to delamination, and can be used in oil and other industries industry. Method of sampling media, subject to delamination,comprises selecting a sampling point from a certain volume of medium, to determine levels of sampling, sample probe is placed in environment of device input element at a predetermined level or levels of selection, a sample is taken. During rest of medium or sample is taken from each level proportional to area of environment, which it fills at sampling level. For a case when medium is movable, said area is defined as product of width of stream at level of sampling and distance, which conventionally would be middle of sampling point for a certain period of time by filling conventionally formed area, while maintaining width of stream. Any of operations for selection of proportion of sample to a predetermined level may be replaced by alternative selection by selection of fraction of sample with other levels, or other level with proviso that when such alternative replacement area levels, which occupies medium - in fact for a medium and conditionally for mobile - can be partitioned, in which ratio of volume of conditional formed partition areas or mass medium filling said areas, is equal to ratio of volume or mass fraction of samples from said areas. In case of separate sampling areas formed conventionally in sample receptacle with subsequent formation of said combined samples formed from combined sample of said fractions from sample volumes which are in same ratio, formed by their respective amounts conventionally formed areas. In case of movable medium, when device is moved together with medium, for producing sampling time period within which width and depth of flow can be considered constant. Device for sampling of media, subject to bundle includes a sample probe element comprising a housing, a cover, speed control filling of sample. Casing of sampling element is designed as a vertical cylinder, in which lower base is entrance to valve. Sample filling speed controller may be configured as a sealed packet interconnected by a side surface of cylindrical sections interconnected with housing and sample probe through valve element. Alternatively sample filling speed regulator can be designed as a piston with a compression spring located between piston and placed coaxially to cylinder cover, wherein connector is located in lid.
EFFECT: high quality of sampling, high representation and high reliability and technological effectiveness of sampling procedure.
