摘　　要：对于露头缺乏和钻井取心较少的海上油田 ,利用测井资料信息量大、数据连续和垂向分辨率高的优势 ,可以间接地从中获取地层岩性、沉积构造、砂体成因、古水流方向、物源方向、砂体迁移方向等多项沉积相标志 ,为下一步进行地层沉积微相研究提供重要依据。海上油田的应用效果表明 ,在综合分析岩心描述、岩矿鉴定、粒度分析、无机地球化学等资料的基础上 ,充分利用测井资料(尤其是地层倾角测井和成像测井资料 )进行油田沉积相研究 ,不仅可以大大节约成本 ,而且有利于开发后期油藏的精细评价和开发方案优化。For the offshore oilfields with rare outcrop data and little core, many useful indicators of sedimentary facies, such as lithology, sedimentary structure, sandbody origin, paleocurrent, provenance location and sandbody migration, can be obtained from well?logging data that is characterized by large information content, continuity and high vertical resolution, thus providing important conditions for further microfacies study. The application of well?logging data has shown that a full use of well?logging data, especially dipmeter and imaging data, in studying sedimentary facies of oilfields may greatly reduce cost and be advantageous to later fine evaluation of reservoir and optimization of development plan, if in combination with core description, mineral identification, grain size analysis and inorganic geochemistry.
