Abstract:

Volcanic-rock reservoir belongs to extremely low permeability gas reservoir. However, as with natural holes and rifts, it can be for industrial development. Relative permeability curve is an important data for dynamic analysis and numerical simulate of gas reservoir development. It illustrated by the case of a Jilin Province's volcanic-rock gas reservoir, and measured the relative permeability curve by unsteady-state water displacement by gas. The results show: It had a high bound water saturation, residual gas saturation and water saturation in isotonic point; it also had a low relative permeability in isotonic point and a low water relative permeability in endpoint; confining pressure and displacement pressure had a significant impact to the results; volcanic-rock reservoir had a serious heterogeneity.

Key words: Volcanic-rock, Extremely low permeability, Relative permeability curve, Core displacement, Unsteady-state
