摘要
苏北盆地高邮凹陷南部陡坡带戴南组储层岩性多样,特别是砂砾岩的存在,使得储层非均质性极强,给油水层识别带来困难。综合利用岩心、测井、试油等动静态资料,研究陡坡带戴南组储层岩性、物性、含油性、电性之间的关系,结合气测、录井等资料确定陡坡带戴南组储层物性与电性下限标准,识别有效储层及精确判断油水层,将建立的油水层识别标准应用到勘探开发生产中,取得良好的应用效果。
Due to various reservoir lithologies, especially the existence of gravels, the strong reservoir heterogeneity causes the difficulty in oil-water layer identification in Dainan Formation in the southern steep belt of Gaoyou Sag. Using the dynamic and static data of core, logging and formation testing, it was researched on relationship among lithology, physical property, oil-bearing and conductivity. And then combined with the gas logging data, it was confirmed the lower limit standards of physical properties and conductivity in Dainan Formation and identified the effective reservoirs and oil-water layers. The identification criterion of oil-water layers was successfully applied in the exploration and development, resulting in good effect.
