چکیده :

 

Permeability and porosity of the reservoir rock has always been considered as two of the most important parameters to identify flow unit for formation evaluation, reservoir description and characterization .The paper describes results of a petrophysical study aimed to improve reservoir description of a complex gas reservoir located in Iran.The hydraulic flow unit (HFU) approach is used in the present study as an integrating tool for petrophysical description of the reservoir. First, we start from a rock type classification based on core data to pick out major HFU constituting the reservoir. We employ combination of routine and special core analysis data to work out a resulting rock type classification for the studied field. Along with description of the HFU classification, we present the underlying geological reasons which control FZI variation for K-field reservoir. Also we present a new method for prediction of permeability in other wells that there isn’t any core data in that. A flow unit is a stratigraphically continuous interval of similar reservoir process speed that maintains the geologic framework and characteristics of rock types.
