Assessment on pore structure of western Sichuan reservoir through mercury intrusion porosimetry

  Mercury intrusion porosimetry injection is important in assessing microscopic pore structure of reservoirs.This paper introduces an estimated function for investigating the pore characteristic of western Sichuan tight gas reservoir based on VG model.Better correlations between the measured and estimated results have been obtained using VG model.Representative parameters were obtained by fitting the predictions of VG model to the experimental data, and then the estimated formulation was proposed for the studied reservoir.Correlation analysis of the parameters of VG model confirms that absolute permeability and irreducible water saturation are important in mercury injection porosimetry.The approach applied in this paper is helpful in investigating tight reservoirs, especially in the common cases when measurement is difficult to carry out, partly because of complicated variability in the field, and partly because measuring is time-consuming and expensive.
