摘要
能谱测井反映地层沉积岩的自然放射性,通过对自然伽马能谱测井资料的地质分析,提取自然放射性铀相对比值和钍/铀比值,用于快速直观地对自然伽马能谱测井资料进行质量监控。目前这种方法在塔河油田奥陶系碳酸岩盐地层的能谱测井资料质量评价中取得了明显的效果。
Spectral log depicts the natural radioactivity of sedimentary rock. Based on a geologic analysis of natural Gamma spectral log data, the author proposed to use the relative ratio of uranium and the thorium-to-uranium ratio extracted from spectral log data for quick quality control of natural Gamma spectral log. This proposed method has been used for quality evaluation of natural Gamma spectral log in the Ordovician carbonate strata in Tahe oilfield.
