| 摘 要： | 储层岩石物理相是储层岩性和物性特征的综合反映,它对油水分布具有重要的控制作用,同类岩石物理相具有相似的岩石学特征,孔—渗关系呈现出规律性变化,表现出相似的岩电关系和测井响应特征。为此充分分析核磁共振、成像测井等新技术,采用测井相分析技术,将储集层划分为不同类型的岩石物理相,在此基础上分类建立了该区块测井参数精细评价模型和油水层判别标准,使研究区的油水层判别精度从原来的60%提高到了80%以上,基本解决了本区油水层判别困难的难题。

| Abstract: | Lithophase is the response of lithology and porosity, and it has an important controlling effect on the distribution of water and oil. Every lithophase have similar logging response, lithology characteristic and relationship of porosity and permeability. In this paper, the logging response of MRIL and FMI have been analyzed by using electrofacies analysis technique. The whole reservoir is divided into several lithophases according to logging response, well logging evaluation models have been constructed, and criterion to identify oil-water layers for different lithophase have been determinated. Through this study, the accuracy of oil-water layer identification has been improved from 60% to 80%, and the difficult problem to identify oil-water layer has been solved. |
