ABSTRACT

At present, global energy conflicts are prominent and the world’s attention is focused on energy security. In order to evaluate the reserves and production capacity of the shale gas, which is a special fossil energy source, the study proposes a reserve and production capacity evaluation design for its reservoirs based on Arps decrement. The study intersects the material balance method and Arps reconciliation decrement method to achieve the evaluation of shale gas reservoir reserves. The shale gas reservoir production capacity was calculated using Integrated Geostatistical and Geomechanical Modeling (IGIG) based on Genliang Guo’s fractured horizontal wells, and Effective Fracture Radius (EFR) formula based on large capsule-shaped flow zones. Experimental data showed that the capacity evaluation method based on the binomial dynamic coefficient inverse calculation of formation pressure can calculate the current unobstructed flow rate and allotted production rate to provide data support for the extraction of shale gas reservoirs.
