Title (EN) SAMPLING TOOL FOR OBTAINING SAMPLES OF FLUIDS PRESENT IN A WELL
(FR) OUTIL D'ECHANTILLONNAGE SERVANT A ECHANTILLONNER LES FLUIDES PRESENTS DANS UN PUITS
Abstract:
(EN) A sampling tool for immersing into a well for collection of samples of oil, gas or water during drilling for production of said fluids. The sampling tool (1) comprises a tubular, hollow and preferably cylindrical member with two chambers (12, 14) separated by a compressible pipe (9). Said sampling tool comprises an outer pipe (2) formed as a cylindrical member to withstand the reservoir pressure. Inside the outer pipe (2) is positioned a unit (13) forming a gas tight storage chamber (12) for the gas-/liquid samples and a chamber (14) for a counter pressure medium. The chamber (14) is formed by pressing the pipe (9) against the inside of a U-profile (10). During sampling, the volume of chamber (12) will increase and the volume of chamber (14) will be reduced corresponding to the increase of chamber (12). Total separation of the gas-/liquid sample from the counter pressure medium is obtained by applying a diffusion tight flexible pipe (9) and the gas-/liquid sample analyzed will thus be representative for the reservoir gas-/liquid sampled.
(FR) Outil d'échantillonnage destiné à être immergé dans un puits afin d'y prélever des échantillons de pétrole, de gaz ou d'eau pendant le forage ou la fabrication de ces fluides. Ledit outil (1) comporte un élément tubulaire, creux et de préférence cylindrique possédant deux chambres (12, 14) séparées par un tuyau compressible (9), ainsi qu'un tuyau externe (2) présentant la forme d'un élément cylindrique afin qu'il puisse résister à la pression du gisement. Une unité (13), disposée à l'intérieur du tuyau externe (2), forme une chambre de stockage (12) étanche aux gaz pour les échantillons de gaz ou de liquide, ainsi qu'une chambre (14) pour un milieu de contre-pression. On forme la chambre (14) en serrant le tuyau (9) contre l'intérieur d'un profilé en forme de U (10). Lors de l'échantillonnage, le volume de la chambre (12) augmente et le volume de la chambre (14) diminue en fonction de l'augmentation du volume de la chambre (12). On obtient une séparation totale de l'échantillon de gaz ou de liquide du milieu de contre-pression en appliquant un tuyau souple (9) anti-diffusion, et l'échantion de gaz ou de liquide analysé est donc représentatif de l'échantillon de gaz ou de liquide prélevé dans le gisement.
