Abstract
The measurement of permeability forms the basis for many engineering and geological engineering investigations. Most of these investigations require that a large number of determinations be made rapidly and accurately. The permeameter discussed here is a modification of the one designed by Ohle (1951). The permeameter allows for rapid sample change and is capable of measuring the permeability of a core sample using any fluid. The permeameter has been used successfully to test permeabilities as low as 10−5 millidarcies to permeabilities as high as 10 millidarcies at fluid pressures up to 10 MPa. The reproducibility of the tests was found to be in the order of 90%.
Résumé
La mesure de perméabilité est la base de beaucoup d'investigations techniques et géologiques. La plupart des investigations exigent qu'un grand nombre de calculs soient réalisés rapidement et avec précision. Le perméamètre dont on parle ici est une modification de celui dessiné par Ohle (1951). Le perméamètre permet un changement rapide d'échantillon et est capable de mesurer la perméabilité d'une carotte de sondage avec n'importe quel liquide. Le perméamètre a été utilisé avec beaucoup de succès pour tester des perméabilités aussi faibles que 10−5 millidarcies jusqu'à des perméabilités aussi fortes que 10 millidarcies à des pressions de 10 MPa. La reproductibilité des essais a été de l'ordre de 90%.
