随着科学技术的发展,地球物理测井方法愈来愈多,并向定量化发展。本文从最基本的静态测井与动态测井原理出发,以自然伽玛测井原理为例,附加了界面的影响,从数学上讨论了测井曲线特点,特别对地层垂向分辨能力的概念做了较详细的讨论。做为对测井资料定量化要求,本文提出对测井资料处理的一般过程,虽对放射性测井方法讨论较为详尽,但做为一般原理,对于其它测井方法以及解释对于区别模拟记录与数字记录也是很有裨益的。
With the development of science and technology, geophysical logging methods are more and more and develop quantitatively. Based on the most basic principles of static and dynamic logging, taking the principle of natural gamma logging as an example, this paper adds the influence of interface and discusses the characteristics of well logging curves mathematically, especially the concept of vertical resolution of formation Made a more detailed discussion. As a quantitative requirement for logging data, this paper presents a general process of logging data processing, although the discussion of radioactive logging methods in more detail, but as a general principle, for other logging methods and explanations for the distinction between analog recording and digital Recording is also very helpful.
