Bestimmung der hydraulischen Durchlässigkeiten eines Sandsteins mithilfe eines Luftpermeameters

Abstract: ZusammenfassungZiel dieser Studie ist die Bestimmung der hydraulischen Durchlässigkeiten eines Sandsteins unter Berücksichtigung der Gesteinsmatrix sowie einer Einzelkluft unter Verwendung eines tragbaren Luftpermeameters. Hierfür wurde der fluviatil-äolisch abgelagerte Bebertaler Sandstein des Oberen Rotliegenden in Sachsen-Anhalt untersucht. Es wurden die Matrixpermeabilitäten der unterschiedlichen Faziesbereiche sowie die Kluftöffnungsweiten entlang einer Schichtfuge bestimmt. Die ermittelten hydraulischen … Show more

“…The block contains one bedding joint with a rough extent of 120 mm in x-direction and 450 mm in y-direction (Figure 1). Previous studies already characterized important hydro-mechanical parameters such as porosity, matrix and fracture permeability, Young's and bulk modulus, thermal dependencies of stress and strain behavior and the mineralogical composition (Frank et al, 2020;Cheng et al, 2020;Fischer et al, 2012;Hale and Blum, 2022;Heidsiek et al, 2020;Hassanzadegan et al, 2012;Blöcher et al, 2019). Of particular interest for this study is the low matrix permeability of 0.1-10 mD, which allows it to be considered almost impermeable (Cheng et al, 2020;Hassanzadegan et al, 2012).…”

“…The fracture sample is a natural bedding joint in a sandstone block taken from a quarry in Bebertal, Germany (Figure 1; Heidsiek et al, 2020;Hale and Blum, 2022). The sandstone is Flechtinger sandstone, an oil and gas reservoir rock in the Northern German Basin.…”
