FIELD: oil and gas industry.
SUBSTANCE: invention refers to subsurface sampling and specifically to continuous measurement of concerned parameters, as well as hydrocarbon sample analysis performed on sampling point after installed in sampling chamber of the downhole device. The device contains downhole sampling chamber for formation fluid sample and control module connected by fluid channel to a part of formation fluid sample in downhole sampling chamber and designed to control concerned parameter of formation fluid sample. Besides method for controlling concerned parameter of formation fluid sample is offered.
EFFECT: provided continuous control of sample integrity including sample surfacing to its delivery to analysis laboratory.
