| 摘 要： | 自然伽玛测井和自然伽玛能谱测井是目前常用的测井方法。作为一种古环境指示曲线,自然伽玛曲线以其灵敏、连续、方便等优点在科学钻探中发挥着日益重要的作用,对短尺度气候事件(如Heinrich事件),自然伽玛测井以其高分辨率仍能精确的探测出来;作为油田、煤田勘查中的主要分层指标之一,自然伽玛曲线现在已经被推广到寻找旋回地层等领域中;而自然伽玛能谱测井仍然是现今探测K、U矿床的重要手段之一,对于在地表或剖面上快速判断K、U异常非常有效。还作为地球化学测井的一部分被应用到科学钻探中,对指示含有U、K、Th等矿物的含量等有一定的贡献。

| Abstract: | Natural gamma-ray logging and gamma-ray spectrometry geological scientific research. As a paleenvironmental index curve, tinuous and convenient, and is playing an increasingly important logging are common used logging methods in natural gamma-ray curve is sensitive, conrole in the scientific drilling. Moreover, it has so high resolution that it can reveal the small-scale paleenvironmental changes, such as the Heinrich event. As a main layered index for oil field and coal field exploration, natural gamma-my can help to discriminate strata and mark small-scale recycle of stratum. Natural gamma-my spectrometry logging is one of the most important methods to indicate K and U beds. As a part of the Geo-chemical loggings, it is applied to the scientific drilling to determine the contents of U, K and Th in stratum. |
