Abstract

Abstract: The cumulative water-injected rate is one of important indices for evaluating the water injection status and effect of a waterflood oil field. The mathematic expressions between cumulative water-injected rate and water cut are deduced and discussed based on the definition of cumulative water-injected rate and water drive characteristic curves, including the expressions for B-type, C-type and D-type curves, taking C-type curve as an example. The theoretical expressions could be as a guide for response evaluation, stimulation and modification of a waterflood oilfield.

Key words: water drive, cumulative water-injected rate, water cut
