Abstract

Analyze of parameters which influence the petrophysical Properties of reservoir rocks is necessary in dynamic model simulation of reservoirs. According to the relation of CEMENTATION FACTOR and reservoir pressure changes, CEMENTATION FACTOR is the most effective parameter in water SATURATION determination in the mentioned model, so the study of the effect of pressure on CEMENTATION FACTOR is necessary. In this study, firstly carbonate core samples of a gas reservoir, in the south of Iran was classified by HYDRAULIC FLOW UNIT delineation method. Then their CEMENTATION FACTORs were determined by Archie equation and best fit curve method at ambient, 800, 2000, 3500, and 5000 psi pressures. The changes in CEMENTATION FACTOR values due to increasing OVERBURDEN PRESSURE were evaluated in each HYDRAULIC FLOW UNIT and their relationship with flow zone indicator (FZI) were studied by experimental equations (for 4 flow units 0.95<R2<0.99). In this study a relation between flow zone indicator for each HYDRAULIC FLOW UNIT and CEMENTATION FACTOR changes, due to the different pressures, were also obtained. The experimental results of studied reservoir cores shows that with increasing flow zone indicator the changes in CEMENTATION FACTORs decreases.
