摘要
针对塔河油田碎屑岩砂体分布规律性差,部分储层开发效果差,引进PSSL全能谱饱和度测井技术,求准剩余油饱和度分布。通过介绍全能谱饱和度测井原理,分析其解释基础和精细解释方法,应用现场实例说明该项技术在薄层分析和厚层细分所具有的优势,并利用该技术确定最佳射孔层位。实践证明,全能谱饱和度测井技术能够准确地评价区分油层、水淹层、水层及干层,正确区分出水淹层的级别,能较好的指导油田采取措施进行开发。
Due to the poor distributive regularity of clastic sandstone in Tahe Oilfield and the poor development of some reservoirs,PSSL poly-spectral saturation logging was introduced to derive a quasi-residual oil saturation distribution.By introducing the principle of poly-spectra,saturation logging and researching the basis of interpretation and the fine explaining method,field examples were used to illustrate its advantages in the analysis of thin beds and the subdivision of thick beds.And the technique was used to determine the optimal perforating horizons.Practice indicates that PSSL can be used to accurately evaluate and identify oil reservoirs,water-out reservoirs,water layers and dry layers and correctly distinguish the grade of water-out reservoirs and guide oilfield taking correct measures for oil development,it is wealthy for popularization.
