Abstract (en)
[origin: WO2014087061A1] - A device for sampling pressurised fluids from a borehole. - The device comprises: -means for holding fluid in a sampling chamber (01), comprising a first piston (05) designed to allow or prevent fluid from entering the lower portion of the chamber, said first piston being moved by means comprising a flexible element (20) placed in a chamber filled with oil and connected to the piston by a rod (04); - means for transferring the sampled fluid, making it possible to control the lowering of a second piston (02) from the upper portion to the lower portion of the chamber, such that the fluid remains at a constant pressure in the chamber (01) during the transfer.
