Water2oil volume ratio of edge-bottom water reservoir
presents the capacity of natural energy. It’s the key to determine
reservoir development scheme and strategy. This article studies
geologic static data and production performance data of actual
reservoir ,combining mterial balance equation ,using unsteady flow
method to calculate water-oil volume ratio of natural water2drive
reservoir , then determines natural energy and reasonable
development scheme , which provides a way for efficient and
economic reservoir developing and plays a certain role for similar
reservoir.
