| Summary | The Sichuan Basin is rich in tight sandstone reservoirs with significant tight gas. However, due to their characteristics of low porosity, low permeability, and strong heterogeneity, conventional reservoir evaluation methods based primarily on resistivity struggle to accurately predict and assess the gas-bearing potential of these tight sandstone reservoirs. Conducting induced polarization (IP) modeling for tight sandstone is critically important for developing new methods of reservoir prediction and evaluation based on IP multi-parameters. Based on the measurements and the analysis of complex resistivity of tight sandstone samples in Zhongjiang gas field, Sichuan Basin, this paper adopted the MGEMTIP model suitable for tight reservoir to carry out IP modeling. A complex resistivity model of tight reservoir controlled by porosity, pore fluid salinity, clay content and saturation was constructed through mineral composition analysis, scanning electron microscopy and anisotropy testing, and the prediction methods of reservoir saturation and permeability were established, which provided a theoretical basis not only for the study of electromagnetic forward and inversion methods, but also for the unconventional reservoir prediction and evaluation. |
