摘要

Hydrologic and geochemical properties were measured on metagraywacke plug samples of matrix rock from shallow and deep cores form The Geysers geothermal field. Gas perme- ability ranged form 2×10~-22 to 4×10~-20 m~2 and Klinkenberg slip factor ranged form 1 to 20 MPa. Porosities ranged form 1.9 to 2.2/100. Capillary-pressure curves were measured and van Genuchten fitting parameters were used to estimate relative-permeability cures.
