Abstract

Permeability can be effected by many factors including effective stress, and this
will further impact the final production of oil and gas. In this work, a stressdependent
permeability calculation model was adopted and based on which a
production function for heterogeneous tight sandstone reservoir on core scale is
derived. Stress sensitivity has been taken as the primary influencing factor to
analysis the impact of effective stress on the productivity of heterogeneous tight
sandstone reservoir. The results shows that the stress sensitivity needed to be taken
into cosideration when the effective stress cannot be overlooked in the design of
developing plan for tight reservoirs; and the severity of the heterogeneity has a
noticeable influence on the production
