| 摘 要： | 地层中富钾矿物的存在使得自然伽马能谱测井曲线的精度降低。根据地层中含Th,K矿物的蕴含特点,分别建立了Th,K含量与粘土矿物含量之间的模型,得到了富钾矿物的校正方法。运用该法对实际资料进行了处理,所得到的结果与实验分析结果对应较好。该方法为富钾矿物的校正提供了一条较为理想的途径。

| Abstract: | Because there exist kalium contained minerals in formation, the accuracy of natural gamma-ray spectrometry logging curve is low. Based on the characters of Th containing and K containing minerals in formation, models used between Th, K content and the content of clay minerals are established respectively for establishing the methods for correcting, kalium contained minerals. The methods are used for actual data processing. The result is consistent with that of experiment. It is ideal way for kalium contained mineral correcting. |
