Abstract:

It is showed that the increasment of the differentid pressure for high liquid production rate of producing wells was one of the main techniques used to enhance oilfield production. In order to determine the reasonable liquid production rate at different water cut stages, we proposed the concept of dimensionless liquid production intensity based on the previous study of dimension less liquid production index, and obtained its theoretical plate according to relative permeability curves. The application showed that the plate of dimensionless liquid production intensity could be used to predict the reasonable liquid production rate and determine the relative values of differential pressure ratio of producing wells at different water cut stages without knowing the differential pressure.

Key words: liquid production prediction, dimensionless liquid production intensity, relative permeability curve, differential pressure ratio
