There are different geophysical and geochemical characters in sediments for their difference of the depositional environments;conversely,the depositional environment of the sediments can be analyzed according to the sediment characters. Natural gamma-ray spectral logging has been extensively used in the study of the Middle and Lower Ordovician carbonates in Tahe oil field.However,content of the natural radioactive elements is rare in the carbonates, and natural gamma is commonly no more than 10 API,so as to the uranium,thorium and potassium curve of the spectrum stripping analysis is low,sometimes amount to zero.So control of the natural gamma-ray spectral logging quality and avoidance of misinterpretation is the important portion in the interpretation of natural gamma-ray spectral log.In this paper,one method is introduced that apply uranium and thorium characteristic curve to control the quality of natural gamma-ray spectral logging,which is simple and easy to put into practice.At the present,this method is well applied to the quality control in logging of the Middle and Lower Ordovician carbonates in Tahe oil field.

沉积环境的差异使得沉积物具有不同的地球物理和地球化学特征,根据沉积物的特征可以分析沉积物当时的沉积环境。自然伽马能谱测井在塔河油田中、下奥陶统地层分析中已经得到广泛应用,但是由于碳酸盐岩地层中自然放射性元素含量很低,自然伽马值一般低于10API,由此进行剥谱分析而得到的铀(U)、钍(Th)、钾(K)曲线也都很低,有时甚至出现回零现象,因此控制自然伽马能谱测井曲线质量,避免误解释是应用自然伽马能谱曲线进行测井解释的重要环节。本文介绍一种利用铀特征曲线(Ut)和钍特征曲线(Tht)对能谱测井曲线质量进行控制的方法,此方法简便易行。该方法在塔河油田中、下奥陶统碳酸盐岩地层中的应用效果明显。
