【摘要】 碳氧比能谱测井方法是在套管井中用于划分油水层、确定含油水饱和度及岩性的一种有效方法。根据碳氧比能谱测井的原始谱线资料 ,提出了一种判断油层水淹程度的指数———水淹指数。通过实际资料验证 ,该指数对水淹程度有很好的判断作用 ,具有良好的应用前景。更多还原

【Abstract】 The carbon oxygen (C/O) spectral well logging is one of the useful and powerful tools in evaluating the reservoir properties in casing borehole. A new ratio was provided in this paper to identify the water flooded degree of oil bearing zone, which we called as water indicator ration, in short WIR, this ratio was proved very effective and useful to identify the water flooded degree in oil reservoir.更多还原
