摘要
Abstract
To address the challenge of evaluating water-flooded zones during the middle-late stages of oilfield development,this study develops and applies a combined detection technology integrating through-casing coring with geochemical analysis,fluorescence thin-section observation,and multi-dimensional nuclear magnetic resonance(NMR).The goal is to overcome the limitations of traditional evaluation methods and achieve high-precision quantitative assessment of water-flooded zones.Results indicate that the proposed combined detection technology enables the establishment of a multi-dimensional evaluation system for water-flooded zones,covering three key aspects:geochemical characteristics,fluorescence feature distribution,and quantitative analysis of pore fluids.Specifically,geochemical analysis accurately identifies the extent of crude oil water washing;fluorescence thin-section observation clearly reveals water-flooding pathways and reservoir sweep ranges;and multi-dimensional NMR precisely quantifies the content and distribution of different fluid types.Practical application in an oilfield block confirms that,compared with traditional methods,the combined through-casing coring detection technology significantly enhances the accuracy and comprehensiveness of water-flooded zone evaluation,and effectively differentiates between strongly,moderately,and weakly water-flooded zones.This technology provides more abundant and accurate data for water-flooded zone evaluation,improving the evaluation efficiency and effectiveness.It also offers a reliable basis for formulating subsequent oilfield development plans,thus exhibiting substantial promotion value in practical oilfield operations.关键词
