Based on abundant information of gamma-ray curves,combining wavelet analysis with fast Fourier transform,the Milankovitch cycle and its thickness of Cretaceous in Wushi sag is identified using frequency spectral analysis,then the sedimentation rates of each layer of Cretaceous in studied area are precisely calculated.
以自然伽马曲线包含的丰富地质信息为基础,通过小波分析与快速傅里叶变换相结合,运用频谱分析法在乌什凹陷白垩系识别出米兰柯维奇沉积旋回,并确定出米氏旋回的厚度,在此基础上精确计算出资料区白垩系各层组沉积速率。
Based on marker bed resistivity,long-spaced gamma-gamma and gamma-ray curves\' abnormal shapes,have verified hosting varying regularity of 9 coal seams in the area,and 2 reverse faults with fault throws of 72.
根据该区标志层的电阻率曲线、长源距伽马—伽马曲线及自然伽马曲线异常形态,掌握了该区赋存的9层煤层的变化规律,并依据测井曲线对比结果发现逆断层两条,其断距分别约为72。
Based on the natural gamma log curves of acid tuff and clay rocks of acid volcanic events,the author here queries the arguments that radioactive intensity of sedimentary strata will grow with the increasing argillaceous materials and that the natural gamma value and the empirical equation can be used to calculate contents of argillaceous materials.
根据酸性凝灰岩和酸性火山事件粘土岩的自然伽马测井曲线,对当前流传的"沉积岩层的放射性强度(或放射性核素的含量)随泥质含量的增加而增高"的概念和用自然伽马值及经验公式求泥质含量提出质凝。
