文章摘要
Abstract: A variety of petrophysical experimental techniques were used to analyze the core samples of the Subei Basin, China, and a three-dimensional digital rock model was constructed. The electrical simulation method based on digital rock model was used to clarify the influence of pore structure and complex mineral components (clay minerals, organic matter, metallic minerals) on rock conductivity in the study area. This study, based on petrophysical experiments and digital core technology, proposes a saturation evaluation model that considers the complex mineral composition of the rock and the pore-throat size classification. The newly developed saturation model, constructed using a tri-pore-throat parallel conductive model and fluid distribution model, has demonstrated excellent application potential in the Subei Basin, China. The findings of this study offer a reliable approach for evaluating the saturation of continental shale oil reservoirs.
