Permeability and Elastic Wave Velocity and Attenuation of Tight Porous Rock

摘要

The study of seismic waves in tight gas sandstones is aimed at determining partial gas saturation in situ from logs. The purpose of the study of the effects of water and its salinity on gas flow in tight gas sandstones is to estimate in situ gas permeability. A completely computer controlled pulse-decay permeability has been designed and constructed.
