THE METHOD OF ZONAL PRESSURE REDUCTION OF OIL TRAP HYDRODYNAMIC MODEL

Abstract

Describing the hydrodynamics of oil trap local area
in terms of coarse geometrics of regular well pattern
zones, results in analysis accuracy decrease due to
equilibrium offset. In this paper computational algorithm of initially detailed element pattern reduction
is considered, that corrects the mentioned drawback, providing for equality of equilibrium states in
full-scale and reduced models. The observing dynamic error of bottom-hole pressure is compensated
by introduction the additional radial near well segment, considering fast hydrodynamics of the well inflow
