Abstract:

Computation modes of remaining economic recoverable reserves in waterflooding oilfields include 4 types of waterfiooding curves,which are suitable for use in layered reservoirs with different crude viscosities respectively.The basic principle for calculating economic recoverable reserves is capital break-even,while waterflooding characteristic curves,oil price and cost should be integrated when calculating economic ultimate water cut.Economic ultimate water cuts are in positive correlation with oil price and commodity rate of crude oil,and in negative correlation with tonnage dues of oil and tonnage operating cost of fluid.

Key words: calculation method, tonnage-operating-cost method, waterflooding, remaining economic recoverable reserves
