"Sampling system for removing contamination from a formation fluid is collected by a tool inside of the well from an underground geological formation and method for sampling ofA fluid for the formation of an underground geological formation through a tool of the interior of the pit. " This is a method and a device for sampling of a fluid of a geological formation.The fluid of the formation is removed from the underground formation to the inside of the inner tool shaft and is collected in a sample chamber.A line of flow output is connected operationally to the sampling chamber to allow the selective removal of a contaminated and / or a clean part of the fluid of the formation of the inside of the cameraSampling, being thus removed contamination of chamber sampling.For example, a clean part of the formation fluid can be made to pass to another board of sampling to be there collected.Or a polluted part can be discharged to the inside of the hole drilled.
