Title
(EN) FOCUSED FORMATION FLUID SAMPLING PROBE
(FR) SONDE D'ECHANTILLONNAGE SPECIFIQUE DE FLUIDE DANS UNE FORMATION
Abstract
(EN)
A formation fluid sampling probe uses two hydraulic flow lines (23a, 23b) to recover formation fluids from both a guard zone and probe zone in a borehole (1) passing thru earth/rock formation (7). The guard zone surrounds the probe zone, thus shielding it from any direct access to borehole fluids. Operation of the tool involves withdrawal of fluid from both zones into a probe sample chamber (27a) and guard sample chamber (27b). Borehole fluids are preferentially drawn into the guard zone so that the probe zone then recovers formation fluid from beyond the mucake (5) substantially free of borehole fluids and drilling fluids. Separation of the guard zone from the probe zone may be accomplished by elastomeric guard rings (15), inflatable packers or coaxial/snorkel tubing. The test tool device having a probe (17), pad (13), clamps (10), fluid ID sensors (19a, 19b) and pumps (21a, 21b) is adaptable for use either on a wireline (3) or in an early evaluation system on a drillstring.
(FR)
L'invention concerne une sonde d'échantillonnage de fluide dans une formation, qui utilise deux conduites hydrauliques (23a, 23b) pour recueillir les fluides de formation à la fois dans une zone de garde et une zone de sonde de trou de forage (1) à travers une formation de terre/roche. La zone de garde entoure la zone de sonde, protégeant celle-ci contre un accès direct des fluides du trou de forage. L'utilisation de l'appareil considéré vise à retirer les fluides des deux zones pour les recueillir dans une chambre d'échantillonnage de sonde (27a) et une chambre d'échantillonnage de garde (27b). De préférence, les fluides du trou de forage sont recueillis dans la zone de garde de sorte que la zone de sonde récupère le fluide provenant des parties situées au-delà de la masse de boue dans la formation, sensiblement sans les fluides du trou de forage. La séparation des deux zones peut être assurée via des anneaux de garde élastomères (15), des renforts gonflables ou un tubage coaxial/d'aspiration. L'appareil, doté d'une sonde (17), d'un tampon (13), de dispositifs de serrage (10), de capteurs d'identification de fluide (19a, 19b) et de pompes (21a, 21b), peut être adapté à une utilisation sur un câble métallique ou dans un système de détection avancée de train de forage.
