通过对感应测井仪器响应函数和视电阻率对地层参数的相对偏导数曲线的考察,本文提出一种考察感应测井仪器响应特性的新方法,发现测井仪器的响应特性不仅与仪器自身结构有关,而且与所测量的地层性质有关,对于仪器设计和地层纵向边界位置的确定提供了理论依据,该方法也可以推广应用到其它电磁感应测井仪器。
Through the investigation of relative partial derivative curves of response logging and apparent resistivity to formation parameters, this paper presents a new method to investigate the response characteristics of logging tools. It is found that the response characteristics of logging tools are not only related to the structure of the instrument itself It also provides a theoretical basis for the design of instrument design and the determination of the vertical boundary position of the strata. This method can also be widely applied to other electromagnetic induction logging tools.
