摘要
基于非线性数学方法,利用录井信息对储层水淹程度进行综合定量评价,是油藏开发方案设计和提高采收率研究等领域的重要研究内容.本文推导了水淹层录井评价的非线性理论模型,编制了水淹层评价软件.结合密闭取心资料,利用编制的软件对地化分析资料、热蒸发烃色谱资料、定量荧光分析资料、核磁共振录井资料、显微荧光薄片资料的水淹响应特征及规律进行分析研究,得到较好的结果.
Based on non-linear mathematical methods, logging information used to comprehensively evaluate water flooding degree of reservoirs has very important meaning to design development program and enhance recovery factor. Non-linear models and software for water-flooded zone logging evaluation are proposed in this paper. Combining the data of sealing core drilling, the water flooding response feature and law of the data of geochemical analysis, pyrolysis gas chromatography, quantitative fluorescence analysis, nuclear magnetic resonance logging and fluorescent thin-section are analyzed by the established software, and good result are found.
