    Fine interpretation method for tight reservoirs based on core experiments and imaging logging: a case study of tight carbonate rocks in L area by Li Dan, Wu Kui, Qi Yu, Yu Shanshan

    Published 2025-04-01
    “…Relationship between lithology and porosity established by conventional logging interpretation is not consistent with the results of gas logging, so it is impossible to accurately determine the reservoir location.MethodThe research in this paper is to interpret lithologic profile based on mineral X-ray diffraction data, to accurately evaluate pore type and permeability based on borehole electrical imaging and multipole array acoustic logging, and to interpret gas saturation by using the Archie formula with variable cementation index.Results and discussionThis method improves the interpretation accuracy of geophysical logging methods for tight reservoirs in this block, and plays a key role in favorable evaluation of reservoir sweet spots.…”

    Logging Evaluation of Mixed-sediments Reservoirs of the Lower Cambrian Canglangpu Formation in Penglai Gas Area, Central Sichuan Basin by WANG Haiqing, WANG Zeyu, LAI Qiang, LI Shurong, WU Yuyu, ZHANG Mingyong, WANG Yaqing

    Published 2024-10-01
    “…From an overall perspective, the regularity of porosity to permeability is poor, the electrical differentiation of gas abundance is fuzzy, so the traditional parameter calculation model is not applicable, and it is urgent to study an effective logging evaluation method. Using the core analysis data such as cast thin section, XRD, physical property, logging data and gas testing data, the paper studied a systematic evaluation method for calculating the mineral component by dimensionality reduction, neural network analysis and element content to mineral content inversion method, calculating porosity by variable matrix parameters on the basis of tri-porosity logging curves, calculating permeability by lithologic subdivision model, and quantitative evaluation of reservoir property, connectivity and permeability by array acoustic wave combined with electrical imaging logging, then determined the lower limit of effective reservoir and the classification standard of reservoir. …”
