高精度碳氧比能谱仪在确定含油饱和度的精度和准确度方面同普通碳氧比测井相比有了很大提高,它可以对0. 8 m 以上的地层做定量解释、对0. 5～0. 8 m 的地层做半定量解释;可以对孔隙度在15 %以上的地层做定量解释、对孔隙度在10 %～15 %的差产层做半定量解释。2000 年9 月—2001 年7 月在胡庆油田7 口井中推广应用,取得了较好的开发效果。实践证明,高精度碳氧比能谱测井能够更精确地反映地层剩余油饱和度的层间分布,能够更加有效地指导油水井开发,为油田后期开发打下坚实的基础。

The high precision carbon-oxygen ratio spectrum logging tool is developed by Daqing Logging Company. This tool can monitor the remaining oil saturation. It can explain the layers which its thickness is more then 0. 8 meters or the porosity is more then 15 percent quantitively or explain the layers which its thickness is between 0. 5 to 0. 8 meters or the porosity is between 10 to 15 percent self-quantitively. Having been applied in 7 wells in Huqing Oilfield since 2000 , get good developing effect was get depend on the logging. In a word ,this logging can reflect the formatian of remaining oil saturation ,and direct the development of the oilfield.
